The Geo-INQUIRE (Geosphere INfrastructures for QUestions into Integrated REsearch) project, launched in October 2022, fosters collaboration between several European research infrastructures, including three key ESFRI European Research Infrastructure Consortia (ERICs), to enhance geoscientific research and innovation. We highlight here those activities within the project that promote synergies between EPOS ERIC (European Plate Observing System), EMSO ERIC (European Multidisciplinary Seafloor and Water Column Observatory), ECCSEL ERIC (European Carbon Dioxide Capture and Storage Laboratory Infrastructure), ChEESE (Centre of Excellence for Exascale in Solid Earth) and the ARISE (Atmospheric Dynamics Research Infrastructure in Europe) infrasound community.
The cross-fertilization approach makes use of EPOS's extensive geophysical and geological data, EMSO's ocean and seafloor observation capabilities, ECCSEL's expertise in carbon capture and storage technologies, ChEESE's advanced pre-exascale computing capabilities for hazard and risk assessment, and ARISE's atmospheric monitoring technologies. Through shared data platforms, interoperable tools and collaborative research workflows, Geo-INQUIRE advances the understanding of Earth processes in both terrestrial and marine domains. Key developments include improved assessments of selected geohazards, insights into marine ecosystems, responses to carbon sequestration, and the integration of innovative deep-sea and subsurface monitoring technologies.
These advances will be made possible by providing users with enhanced services integrating new multidisciplinary FAIR data, integrated workflows, training modules, transnational access at key testbed sites, and management policies and KPIs essential for infrastructure governance. This collaborative framework demonstrates how coordinated efforts between research infrastructures (ERICs) can strengthen the European geoscience research landscape and foster multidisciplinary approaches to address critical global challenges. The project highlights the importance of open data sharing and interoperability standards to maximise the societal and scientific impact of research infrastructures.
The presentation will describe the envisaged approach during the proposal preparation phase, the current state of play, and finally, highlight the challenges with the evolving landscape of the project, with use cases shifting from an early emphasis on FAIR data only to a growing focus on AI-driven applications. In addition, the project addresses the rapid updates of data management policies in different communities, while providing a common framework of Key Performance Indicators (KPIs) for data providers, infrastructure operators and other stakeholders. The scientific focus is also evolving during implementation, from an initial focus only on the land/sea interface to also preparing for future climate and biological applications through AI-ready geoscientific data and services, which are becoming a critical asset for understanding the drivers of climate change.

The Geo-INQUIRE (Geosphere INfrastructure for QUestions into Integrated Research project - www.geo-inquire.eu) aims to foster the curiosity-driven research about solid Earth. Monitoring dynamic processes within the geosphere requires facilitated access to data, data products and services in a wide range of geoscientific disciplines.
A particular focus on georesources is addressed by using two operational research infrastructures, EPOS (European Plate Observing System) and ECCSEL (European Carbon Dioxide Capture and Storage Laboratory Infrastructure) with innovative activities to extend and enrich the existing underlying thematic data services. While EPOS provides virtual access to data and information over large territories in Europe and worldwide, ECCSEL primarily produces local experimental datasets at lab facilities level in Europe. Four thematic communities teamed up to concretise the cross-domain scientific activities, both from the data provider and end user sides: EPOS -geology, induced seismicity, geodesy- and ECCSEL -permanent CO2 storage, temporary subsurface feedstock storage (H2 and derivates, heat, air, CO2), geothermal energy-.
Halfway through the project implementation, the collaborative work of the stakeholders results in strengthening the respective data contents and management structures enabling their connections. In France, the induced seismicity fact sheets recorded in the CDGP (Data Centre for Deep Geothermal Energy) are now better documented with geological maps and boreholes as well as geodesy and petrophysical properties. The anthropogenic hazards events capitalised and disseminated through the EPISODES platform offer access to episodes and information about boreholes located in their vicinity, being both the source of seismicity and monitoring locations. This enhanced virtual access to these induced events will soon be available on the EPOS data portal. The bridge between EPOS and ECCSEL research infrastructures is now enabled through the integration of a first set of boreholes and experimental data of two platforms in Norway and Italy to be accessible on the EPOS data portal through the national borehole database e-nodes.
The presentation will also expose how this cross-domain data access is enabled through semantic and technical interoperability in line with the FAIR principles to guarantee an efficient and reliable access to research contents.

The rapid evolution of cross-disciplinary research in geoscience has led to an exponential increase in complex data production, significantly challenging the data research experts as well as the data repositories management. This complexity is evident in large-scale data infrastructure projects like the EU-funded Geo-INQUIRE project, which includes five major Research Infrastructures (RIs) in geoscience, namely EPOS-ERIC, EMSO-ERIC, ECCSEL-ERIC, ARISE and ChEESE, offering both Transnational Access (TA) and Virtual Access (VA).
Integrating data from TA into a unified VA systems often presents challenges, particularly in multi-institutional projects. This process requires significant expert intervention and frequently results in excessive meetings and potential integration failures.
To address this, the current contribution proposes a novel data science-driven method targeting research infrastructure governance challenges. The approach introduces an automated analytical framework to guide the integration of TA assets into VA systems. Leveraging Large Language Models (LLMs) for semantic embedding, the method transforms unstructured metadata from VA and TA sources into structured data vectorizations. This cohesive data frame then undergoes a series of similarity analysis techniques based on cross-semantic embedding evaluations. Using data from the multidisciplinary Geo-INQUIRE project, the method's is tested for its ability to manage complex asset integration across five major geoscience RIs.
The primary finding offers a preemptive framework streamlining connections for integrating TA assets into appropriate VA systems, facilitating decision-making on asset integration flow.
The resulting mapping not only optimizes TA-VA asset matching but also uncovers cross-connections between installations (services), inter-RIs, and potential multi-institutional collaborations. Furthermore, the research presents complex scenarios, through idealized simulations based on TA-VA metadata variable changes, proposing alternative integration pathways when minor asset adjustments or asset enhancements are implemented at the VA installation level.
This contribution is a proof-of-concept research based on a data-driven solution aimed at streamlining data integration in large-scale geoscience projects. It could potentially reduce expert intervention, enhance cross-disciplinary research opportunities, and improve overall efficiency in managing complex, multi-institutional data infrastructures.

The Earth System is a complex and dynamic system that encompasses the interactions between the atmosphere, oceans, land, and biosphere. Galaxy is an open, comprehensive, and sustainable web platform for understanding and analyzing data from the Earth System sciences, which is essential, for example, to study the impacts of climate change.
Therefore, Galaxy can be used as an IT toolkit for multidisciplinary and interdisciplinary studies with a set of tools for data visualization, analysis, and processing across various scientific fields such as oceanographic, atmospheric, land sciences, and more. By design, Galaxy manages data by sharing and publishing results, workflows, and visualizations, ensuring reproducibility by capturing the necessary information to repeat and understand data analyses. Thus, Galaxy for the Earth System sciences aim at directing users toward standardized tools that can be plugged into cross-domains workflows.
Fully integrated into the work area, the Galaxy Training network (available at training.galaxyproject.org) is an initiative that aims at making the Galaxy platform accessible to a wide audience by providing free and open educational resources. It offers an extensive collection of detailed and reviewed tutorials authored by administrators, developers, and scientists. These tutorials serve as valuable resources for individuals seeking to learn how to navigate Galaxy, employ specific functionalities like tools or execute workflows for specific analyses. By mixing trainings and tools in the same friendly user webapp, Galaxy is a tool perfectly suited for open science.
As part of the FAIR-EASE project, we have deployed a Galaxy adaptation for Earth System studies (earth-system.usegalaxy.eu) with dedicated models, data, tools and data visualisation. We want to use this opportunity to present during your session a set of workflows and trainings mixing in-situ and biogeochemical ocean data, atmospheric volcanoes data, and marine biodiversity data. Our goal is to showcase the possibility to have multiple scientific domains studied and visualise several data types of the same geographical area in one virtual research environment.

When referring to Earth Observation data, we consider two sides of the same coin: space-based data and in-situ data collected on or near to the ground. While satellite-derived data benefits from a consolidated data management and sharing practices, in-situ data is more complex, highly heterogeneous by nature, involving a wide range of actors and data sources, which creates significant challenges in making this data standardised, integrated and interoperable, and ultimately, accessible and usable.
Willing to address these challenges, the InCASE project —supported by the European Environment Agency and funded by the European Commission as a contribution to the Group on Earth Observations (GEO)— developed the Geospatial in-situ requirements (G-reqs) tool. Designed primarily to support GEO Work Programme activities but open to contributions beyond GEO, G-reqs acts as a database and a standard methodology to collect and manage user requirements for in-situ datasets.
The development of G-reqs was done with the hope that the content generated will help in identify shared requirements across domains, detect barriers and gaps, and act as a bridge between user demands and data providers by facilitating the matchmaking between the required and the produced data, or even to prioritize new in-situ data collection strategies. During the last year, the focus was on engaging with the user community to collect as many requirements as possible trying to avoid bias in particular theme, backgrounds, or geographic regions.
In this communication we analyse the content of the G-reqs and discuss to what extent it can fulfil the hopes described before via a series of showcases and statistical overalls. The presented approach demonstrates user-driven solutions and the significance of initiatives like GEO in advancing Open Science and extract new knowledge enabling cross-domain interaction for environmental research and decision-making.

Case Study of Vertical Interoperability Between Research Tools Enabling an End-to-End Sample Workflow from Collection, to Management, to Archiving
Vertical Interoperability
In recent years, interoperability has taken the forefront of discussions on research data management, whether related to research tools, data, or metadata. When it comes to research tool interoperability, the focus so far has been horizontal, improving the flows between tools that serve the same category: GREI’s standardisation of generalist repository metadata [1], a DMP Common Standard [2].
However, the data and metadata is also going to flow vertically, across tools used in very different stages of the research process. These tools will naturally have different requirements, focuses, and functionality from each other, especially differing between domains. How can we enable information to flow between these tools while ensuring FAIR principles are upheld? How can we facilitate researcher processes while ensuring traceability and no metadata loss? What considerations need to be taken into account by institutions and tool developers to design a flexible solution that satisfies user needs?
Case Study - Fieldmark, RSpace, repositories
In this presentation, we will provide an update on the development of our end-to-end, integrated research data management workflow for samples. We integrate three tools, covering sample collection, processing, storage, and archiving:
- Fieldmark, an offline sample metadata collection tool
- RSpace, an ELN and sample management system and RDM platform
- Generalist and domain-specific data repositories
The presentation will also explain how consistent use of IGSN IDs (the material sample persistent identifier) in every tool and at every stage of the process acts as an integrating force and enhances data discovery.
We wish to present both practical recommendations, as well as higher-level reflections on how to approach thinking and developing vertical interoperability at an institution, and its benefits for researchers and RDM as a whole. We will also cover planned support for PIDINST. We hope that attendees will gain a strengthened mental model of how their tools ecosystem could interact, and how to approach building greater interoperability in their workflows.

Spaceborne Differential SAR Interferometry (DInSAR) is a widely exploited technique that allows measuring ground displacements with centimeter/millimeter accuracy at a large spatial scale. The recent availability of worldwide DInSAR measurements, as well as their standardization in terms of format and access procedures, has further pushed this technique toward its application and integration with other data sources for carrying out multidisciplinary analysis of natural and anthropogenic surface deformation phenomena. In the following, we show some examples carried out in volcanic and seismic areas, testifying the capability of the DInSAR technique to be exploited in multidisciplinary contexts.
For what concerns volcanic scenarios, we focus on the Campi Flegrei caldera (Italy) which is experiencing a continuous ground uplift since 2005, with a main radial pattern centered in the Rione Terra district of Pozzuoli. The analysis of detailed DInSAR measurements, retrieved by processing image time series acquired by the Copernicus Sentinel-1 and the Italian COSMO-SkyMed SAR constellations, allowed the identification of a geodetic anomaly in the Campi Flegrei long term uplift pattern, i.e. an area that shows a deficit in the uplift. The amount of this deficit has been analyzed by also considering other data sources, such as the seismicity of the area, showing a high correlation factor. In addition, the location and spatial extension of the anomaly have been further demonstrated to be related to the geology of the area. These findings provide intriguing insights into the volcanic evolution process and the related hazard.
With reference to the development of seismic analysis, we concentrate on EPOSAR, which is an operative service based on Copernicus Sentinel-1 data deployed by CNR-IREA, that allows generating, at the global scale and in a systematic way, co-seismic DInSAR ground displacement measurements once the satellite data are available after a major earthquake (Mw>5.5, ipocenter depth < 20km) occurrence. These products are automatically provided to the scientific community through the EPOS data portal according to a defined standard. The availability of these kinds of measurements also allowed the development, in collaboration with INGV, of a new service that operates in a cascade to the previous one and retrieves the seismic source that generated the earthquakes. To this aim, the DInSAR measurements are jointly exploited with the available seismic moment tensors provided by the main global seismic services (e.g., USGS and INGV). This automatic service is another example of multidisciplinary data integration and it is worth noting that it strongly benefits from the open access and interoperability policies adopted by the respective data providers.

Abstract: The Yilgarn Craton in Western Australia, one of the world's oldest cratons, is rich in mineral resources and provides significant opportunities for research into geothermal energy, crustal dynamics, and mineral exploration. To investigate the electrical structure of southwestern Western Australia, we interpret magnetotelluric data using a finite element-based inversion algorithm we developed, complemented by Bouguer gravity anomaly data, and perform a detailed analysis of the crust-mantle electrical structure. We rigorously validate model sensitivity and cross-verify the inversion results with those obtained using ModEM and Bouguer gravity anomaly interpretations. Our findings identify the Darling Fault and the southern Manjimup Fault as critical structural boundaries that delineate distinct geological features in the study area. All three methods consistently reveal low-resistivity anomalies in the asthenosphere at depths shallower than 100 kilometers. By integrating these results with insights from seismology, gravity, geodynamics, and geochemistry, we suggest that significant geological activity occurs beneath the ancient crust of the Yilgarn Craton. The observed low-resistivity anomalies likely result from the influence of the Darling Fault, the southern Manjimup Fault, and early magmatic processes associated with the craton’s evolution.

Whilst earthquakes cause destruction, the faults along which they occur are responsible for building varied landscapes and influencing ecosystems by controlling topography, hydrology, soil properties, and vegetation patterns. Faulting acts as both a water conduit and a hydrological barrier, channeling groundwater and creating localized zones of moisture retention. Surface faulting and the resulting topographic complexity contribute to heterogeneous vegetation patterns, with denser vegetation often developing along steep fault escarpments where grazing and agricultural activities are limited. Erosion along fault scarps enriches soils with nutrients and clays, supporting vegetation growth, while also posing risks such as the release of harmful substances like fluoride and arsenic, especially in geothermal regions.
We carry out a broad interdisciplinary study within the East African Rift System to explore the connections between tectonic processes and ecosystem dynamics. By combining geomorphological analysis, soil and geochemical studies, and remote sensing techniques, we investigate how faulting shapes soil fertility, hydrology, and vegetation patterns in these regions. Here, we focus on three illustrative case studies: the southern and central Kenyan Rifts and the Serengeti-Mara ecosystem.
In the southern Kenya Rift, fault-driven erosion and volcanic ash deposition around Lake Magadi enhance soil fertility, sustaining vegetation in this climatically vulnerable area. In contrast, uplifted footwalls and eroded substrates exhibit nutrient deficiencies, limiting ecological productivity. In the central Kenya Rift, near Lake Nakuru, elevated fluoride levels in ground- and surface water are among the highest globally and pose significant health risks to humans and animals. Fluoride concentrations are driven by the naturally high fluoride content in trachytic pyroclastics, which leach into the hydrological system through geothermal activity along active normal faults.
The Serengeti-Mara ecosystem is largely situated on the ancient continental crust of the Tanzanian Craton, where fault activity in the northern and southeastern sectors locally enhances soil moisture and vegetation stability. These tectonically influenced areas provide fertile hotspots within a landscape otherwise characterized by highly dynamic seasonal vegetation patterns. This patchy nutrient distribution is crucial for grazing animals, whose migrations are shaped by the shifting availability of fertile areas, driving ecological connectivity and long-term resource distribution.
Our studies highlight the dual role of fault activity in sustaining biodiversity while presenting challenges through earthquake activity and the release of potentially harmful elements. These findings contribute to a broader understanding of the interplay between geological processes and ecological resilience in tectonically active landscapes.

The Irpinia Near Fault Observatory (INFO) is a state-of-the-art infrastructure for monitoring seismic activity in the Southern Apennines, a region of high seismic hazard that experienced the 1980 M 6.9 Irpinia earthquake. Managed by the University of Naples, the observatory operates the dense ISNet seismic network, including 30 strong-motion and short-period sensors, 9 broadband seismometers, as well as geodetic and geochemical stations from INGV. Data and products are openly shared through the EPOS platform and the FRIDGE community portal. INFO also serves as a testbed for the Geo-Inquire project, providing unique transnational access for geophysical surveys and real-time analysis.
Fifteen years of continuous seismic monitoring have uncovered a strong correlation between the hydrological loading of shallow karst aquifers, GNSS-measured surface deformation, changes in elastic properties of subsurface, and seismicity rates at depths where large historical earthquakes have nucleated. Velocity and attenuation tomography have further revealed the pervasive presence of deep fluids, with evidence of reservoirs likely containing CO₂ and brine.
Despite these findings, the background seismicity in the area appears sparse, with hypocenters distributed irregularly within the graben system bounded by the faults responsible of the 1980 earthquake. To better understand the microseismicity pattern and its relationship with the major fault structures, we deployed a temporary dense network of 20 arrays (10 stations each) for one year (DETECT experiment), alongside with a Distributed Acoustic Sensing (DAS) system monitoring a 20 km fiber-optic cable.
Advanced machine learning detection techniques, applied to data from the dense monitoring network, expanded the standard seismic catalog by a factor of eight, producing a dataset comparable to a decade of traditional observations. The enhanced catalog revealed that seismic events follow the seasonal hydrological loading, predominantly cluster at depth, forming small sequences of aftershocks (magnitude <1) that trace a 20–30 km long structure with a stepover. The DAS system has provided coherent recordings of deep phases, likely reflecting the interface between the carbonate plate and the crystalline basement. These insights have paved the way for the installation of permanent arrays and DAS systems in the area, expected for 2025, enhancing the observatory's capability to unravel the complex interplay between seismicity, deep fluids, and external forcing mechanisms.

It is widely acknowledged that ‘putting FAIRness into practice’ with respect to cross-disciplinary data sharing demands overcoming domain-specific practices regarding data dissemination. I.e., communities may rely on specialized standards for describing and sharing data (metadata, vocabularies, services) that do not always easily allow for successful reuse in other domains and may as such not be directly fitted for cross-disciplinary research. In the Geo-INQUIRE project (https://www.geo-inquire.eu/) the European ESFRI landmark research infrastructures EPOS, EMSO, and ECCSEL, the Center of Excellence ChEESE, and the ARISE infrasound community collaborate in overcoming cross-domain barriers, especially the land-sea-atmosphere environments, thereby exploiting innovative data management techniques. As such, one of the strategic priorities of the project is to ‘enhance FAIRness of all data and data products’ for the research infrastructures involved. This concerns not merely a one-time application of the FAIR principles as far as possible, but also measuring the impact for research communities through the establishment of a feedback loop and the measurement of appropriate performance indicators which must be taken from a feasible metrics framework for FAIRness. This approach allows for a constant improvement of data and data products from the FAIR perspective.
The challenges that follow from this ambition are three-fold: 1) In the light of the variety of specialized sub-communities there is the demand to decide about the distinction of intermediate levels for harmonization of metadata, vocabularies, and services design; 2) An instrument is required to perform the actual assessment on the basis of the adopted FAIR metrics framework (thereby following the harmonized standards at the appropriate level), and which must be ready for use by data and/or installation managers; 3) A feedback loop must be configured to support the monitoring of impact and improvement with respect to FAIRness.
To meet these challenges within Geo-INQUIRE we used valuable outcomes from external initiatives (e.g., FAIRsFAIR, GoFAIR). For the FAIR assessment we developed the Geo-INQUIRE FAIRness Assessment Pipeline, a system that evaluates the FAIRness of multiple datasets over time by means of the F-UJI tool in the background, while providing a GUI to analyze the results through multiple dimensions and levels of classification (e.g. discipline). Evaluation over time tracks improvement in a quantitative manner and provides a powerful instrument for creating increased awareness.
For the process of community harmonization at the appropriate intermediate levels we turned to the use of FAIR Implementation Profiles (FIPs). The results we share offer an interesting example of an approach that could easily be transferred to many different cross-disciplinary contexts.

The Geo-INQUIRE (Geosphere INfrastructure for QUestions into Integrated REsearch) project, supported by Horizon Europe, aims to improve geoscience research infrastructures and services to make high-level data and products available to the broad geosciences research community. The goal of the Geo-INQUIRE project is to encourage curiosity-driven research to understand Geosystem processes at the interface of the solid Earth, oceans and atmosphere using big data sets, high-performance computing methods and state-of-the-art facilities.
The project places great emphasis on supporting the dynamic development of data and services through the effective use of Research Infrastructures such as EPOS, EMSO, ECCSEL and ChEESE. Training, networking and community building are the key to supporting it. The methodology ensures the strengthening of the participation of both young and experienced researchers and the inclusion ofoften underrepresented communities. It incorporates also new and cross-cutting perspectives, while addressing current major environmental and economic challenges as well as stimulating curiosity-based and interdisciplinary research.
Project dissemination activities include a series of open online training and more specialized on-site workshops focusing on data, data products and software solutions. Scientists, early-career scientists and students are communities that are able to explore various fields of science related to the geosphere, even those not directly related to their field, with possible connection through research infrastructures. Through lectures and use cases, we show and teach how to use data and information from interdisciplinary research infrastructures. We raise awareness on the potential and possibilities of Research Infrastructures contributing to Geo-INQUIRE, as well as data integration and the importance of FAIR principles. The training offer is constantly updated on the project website www.geo-inquire.eu.
In autumn 2025 the second summer schools will be organised in Catania, Sicily, and will be dedicated to cross-disciplinary interactions of solid Earth with marine science and with atmospheric physics. The second call of the personalised training program, supporting short research stays, will be announced in 2025. Moreover, after the first two successful calls, the 3rd call for Transnational Access to Research Facilities is open until the end of February 2025. The final 4th call will open in late spring/early summer. Data and products generated through Transnational Access will be made available to the scientific community at large in strict adherence to the FAIR principles.
Geo-INQUIRE is funded by the European Commission under project number 101058518 within the HORIZON-INFRA-2021-SERV-01 call.

The EPOS TCS Multi-Scale Laboratories (MSL) collects and harmonizes both available and newly emerging laboratory (meta)data, thereby aiming to generate data products that are easily Findable, Accessible, Interoperable and Reusable (FAIR) for future research, notably into Geo-resources, Geo-storage, Geo-hazards and Earth System Evolution. Key for discovery of MSL data is the use of well-established and openly published controlled community vocabularies. These vocabularies provide all terms for a full contextual description of a conducted laboratory experiment (e.g., materials used, apparatus, etc.). To improve the findability of future data publications we provide (metadata) editor components which connect to the community vocabularies. These vocabularies themselves are openly accessible and ready for incorporation in existing data publication chains at data repositories.
Challenges arise especially with respect to legacy content stemming from the long tail of science, i.e. data that were published before the MSL community standards for metadata and vocabularies became available. In many of such cases the presence of standardized metadata for discovery and provenance is often limited. To improve the findability of these valuable but non-harmonized data publications we developed a strategy which makes use of the MSL vocabularies. With this strategy we demonstrate how controlled vocabularies can be used for filling metadata gaps in older data publications and as such can be useful not merely for new data publications, but for the improvement of FAIRness for older sets as well.
The first challenge we faced concerned the identification of relevant legacy content that had to be discovered within the large offering at repositories. Using controlled term recognition we were able to identify a large set of data publications that appeared to be relevant to the MSL community. The second issue to solve was the enrichment of metadata to improve the findability of the identified publications. The use of the MSL vocabularies in combination with a textual analysis of the collected abstracts and titles allowed for an hierarchical description of the data, the experiment itself, and the equipment used. The result was an improvement of the findability through an extension of the initial metadata.
The extended metadata is shared via the EPOS Platform (https://www.ics-c.epos-eu.org/) and the MSL community data catalogue (https://epos-msl.uu.nl) which guides users in finding data publications through the provision of hierarchical filtering options with increasing granularity. The methodology we describe could be applied in broader contexts within the solid Earth sciences.

CyCLOPS is a strategic research infrastructure unit led by the Cyprus University of Technology Laboratory of Geodesy, designed in collaboration with the German Aerospace Center (DLR), and supported by government agencies and European initiatives. CyCLOPS is Cyprus’ first and only Tier-1/ Class-A permanent GNSS station network designed to monitor geohazards and densify global and regional frames in the country. Its main objectives are to precisely estimate ground displacements at the national level, bolster resilience to seismic and geological threats, and establish Cyprus as a dedicated calibration site for SAR satellite missions.
Co-located with highly precise tiltmeters, weather stations, and calibration-grade corner reflectors, this infrastructure provides millimeter-level positioning and velocity estimates, revealing critical insights into the island’s geodynamic regime. The CyCLOPS strategic research unit integrates GNSS data with InSAR products — DInSAR, PSI, and SBAS — to expand deformation spatial resolution beyond GNSS’s single-point observations. Using corner reflectors designed with the DLR, CyCLOPS enables multi-track calibration for ascending and descending satellite orbits, which are particularly important for studying tectonic shifts along the Eurasian-African plate boundary. To date, the infrastructure has identified the tectonic motion of Cyprus and monitored active landslides with considerable weekly velocity.
In addition to its permanent segment, CyCLOPS features a mobile segment equipped with GNSS stations of the same grade, tiltmeters, and electronic corner reflectors that can be swiftly deployed to areas prone to geohazard risks, such as landslides or rockfall zones. The Operations Center (OC) manages storage, analysis, and dissemination of both GNSS and InSAR data products. Leveraging a cloud-supported, mixed microservices architecture, the OC delivers daily positions of ground stations and their quality assessment, real-time alerts for abrupt events, and monitors the infrastructure operating status.
Beyond national priorities, another key objective of CyCLOPS is to support regional and global infrastructure initiatives. To that end, CyCLOPS already contributes three GNSS CORS to the European Plate Observing System (EPOS), and one station to EUREF’s EPN.
CyCLOPS+ marks the next expansion phase aiming to establish a continuously updated Cyprus Ground Motion Service (CyGMS) by densifying the existing network with at least five new Tier-1/Class A GNSS CORS sites, and more electronic corner reflectors (ECR-C) to enhance both real-time and post-processing analysis. An important outcome of CyCLOPS+ will be a robust national velocity model that will complement and calibrate the European Ground Motion Service (EGMS) by filling spatial coverage gaps and addressing reference frame challenges. Finally, CyCLOPS+ aims to improve national disaster preparedness, inform infrastructure planning, and provide critical data to authorities responsible for safeguarding communities against seismic hazards, landslides, and other geological threats. Through close collaboration with government agencies and stakeholders, CyCLOPS+ aims to position Cyprus at the forefront of integrated ground motion monitoring in the Eastern Mediterranean region.

The EPOS-Norway – Research Infrastructure for Geohazards (EPOS-NG) will be established, starting from spring 2025, with funding from the Research Council of Norway’s Infrastructure program. EPOS-NG aims to be the go-to infrastructure for research on geohazards in Norway (i.e., landslides, tsunamis, earthquakes, and cryospheric hazards). Complementary to EPOS ERIC and building on research infrastructure developed during EPOS-Norway (EPOS-N) phase 1, EPOS-NG will establish new pools of instruments that are easily accessible to all geoscientists in Norway. We will develop an enhanced and extended state-of-the-art data portal to provide nationwide access to a range of geoscience data as well as computational and visualisation services. The EPOS-NG instrument pools include rapid-deployable seismometers, ocean bottom seismographs, Distributed Acoustic Sensing and Distributed Temperature and Strain Sensing instrumentation, Transient Electromagnetic measurement capacity, piezometers, self-potential sensors and ground-based interferometric radar systems. The new instruments will facilitate research on a wide range of processes including seismicity, slope stability and landslides, groundwater and soil conditions, permafrost and cryospheric processes. Combined with new services for tsunami hazard assessment, as well as novel datasets on InSAR displacement trends and historical and palaeoseismological events, new links can be established through comprehensive, multidisciplinary studies. Effective data integration and visualisation will be achieved via the EPOS-N portal, which was developed in EPOS-N phase 1 and will be substantially enhanced in close dialogue with the users in EPOS-NG. The portal combines data from distributed monitoring networks, innovative services for advanced data analysis and national databases within geosciences into a single national e-infrastructure, following FAIR principles. EPOS-NG thus represents a unifying nationwide research infrastructure, including all the relevant physical infrastructures and providing a national hub for solid Earth science data and services.

Earthquakes can affect societies causing dramatic effects in both the built and the natural environments. Greece is characterized by the highest seismicity in the Mediterranean region, with a record of earthquakes and associated phenomena from antiquity up to the present. We organized for the first time a unified earthquake impact database covering the Greek territory from AD 1800 up to 2024, which include building damage and rates of fatalities and injuries. Data about earthquake secondary effects have also been inserted in the database concerning several types of ground failures, such as co-seismic landslides, soil liquefaction, surface fault traces, ground fissures, other environmental changes and tsunamis. The new Greek earthquake impact database (GEID), apart from the descriptive information of an earthquake, also provides parametric attributes such as earthquake epicentre, focal depth magnitude and intensity. The GEID is of great importance since it may help in studies such as a better understanding of the seismic hazard and risk in Greece and its surroundings.

The EPOS-GNSS Data Gateway (DGW) is the European thematic gateway to GNSS data distributed within the European Plate Observing System - EPOS framework. Thanks to this portal, all interested parties have free access to metadata and data from over 2,000 European GNSS stations.
The information system is based on a network of servers, the nodes, connected to a main server, the DGW. The main showcase is the DGW's graphical interface (https://gnssdata-epos.oca.eu/), which enables all the data and metadata in the EPOS-GNSS data infrastructure to be browsed and downloaded. It conceals a complex system of multiple software enabling the integration and synchronization of metadata between the DGW and the nodes. The development and population of this system is the result of a team effort involving the development team, node managers and the node infrastructure and DGW operation coordination team (https://gnss-epos.eu).
New features for 2024 include the integration of two new nodes (CEGNxEPOS, Italy and SONEL, France), filling a gap in Central Europe (Northern Italy, Austria, Slovenia) and opening up to other scientific communities, such as those working on long-term sea level trends as part of GLOSS (Global Sea Level Observing System). Their deployment and population, at record speed, demonstrate the commitment of the new partners, the robustness of the system and the efficiency of the procedures. Next, the level of data completeness at the DGW in relation to the stations proposed to EPOS is becoming very good. Finally, the number of files not validated at the nodes, according to the EPOS-GNSS procedure, and therefore not transmitted to the DGW, is now very low.
On the other hand, there are some important novelties worth highlighting. All the monitoring tools needed to check that the entire system is working properly are now operational. These tools focus on monitoring all system elements and their interaction at the DGW, comparing metadata between the DGW and the nodes that highlights metadata and synchronization issues, monitoring availability statistics for each DGW-hosted service and user statistics. The system also now gives the opportunity to publish hourly High-Rate GNSS data that are accessible at both the DGW and the EPOS multidisciplinary platform. In early 2025, a new version of the graphical interface, developed using a different technology, will be deployed, enabling easier customization of the interface by node managers, in particular to better acknowledge all contributors to the EPOS-GNSS system.

ISPRA has developed a platform for the collection and analysis of data from a continuous hydrogeochemical monitoring network in the framework of MEET (Monitoring Earth’s Evolution and Tectonics) project, funded by the Ministry of Research (MUR) through the National Recovery and Resilience Plan (Mission 4, Component 2, Investment Line 3.1). The platform allows for near real-time transmission of physico-chemical parameters such as water level, temperature, and electrical conductivity from wells and springs monitored using automated instrumentation.
Hydrogeochemical data, when systematized and integrated with geophysical and geological parameters, are useful for understanding seismic and volcanic activity at different temporal scales, as well as for monitoring water quality and quantity, i.e. environmental protection purposes. Hydrological variations (piezometric levels, spring flow rates, chemical and temperature changes) can reflect changes in the stress field within the Earth's crust. For instance, significant hydrological variations were observed during major earthquakes such as L'Aquila (2009), Emilia (2012), and Amatrice-Norcia (2016), as well as during historical events. However, in non-volcanic areas of Italy, systematic and prolonged monitoring of these parameters is still lacking.
Recent advances in geophysical prospecting and the analysis of hydrogeochemical variations related to volcanic and seismic phenomena have provided valuable information for identifying possible precursors. The existing monitoring network will be expanded with new stations provided by INGV, located at sites identified by ARPAs.
The collected data will be stored in a hybrid cloud system, based in ISPRA, to ensure access, interoperability, and continuous sharing of data at a transnational level, complying with INSPIRE technical standards and the FAIR principle. A new architecture has been designed to collect historical and real-time data, ensuring high quality and compliance. This includes an innovative engine for data storage, validation, and querying, which serves as the core of the system.
The system uses a No-SQL database with native APIs, enabling the publication of data through interoperable OGC INSPIRE services and interactive access via a responsive platform. The choice of a flexible search engine was driven by the need to handle an increasing volume of real-time data while maintaining high performance. An ETL (Extract, Transform, Load) procedure was implemented to transform the relational model into a document-based model, optimizing indexing and enhancing system performance. This approach allows response times up to ten times faster than the previous system.
Data governance is a critical aspect: a well-documented process has been defined to ensure quality and efficiency throughout the entire production cycle. The integration of these technologies significantly enhances monitoring and analysis capabilities, contributing to the development of a national and transnational network for hydrogeochemical and environmental monitoring.

An earthquake doublet with magnitudes Mw7.8 and Mw7.6 struck southeastern Turkey on February 6, 2023, causing widespread loss of life and property. To evaluate the seismic damage across 11 affected provinces, we conducted a comprehensive analysis of strong motions and building damage. Specifically, we analyzed the statistical and spatial ground motion intensity measures, along with special characteristics of near-fault pulse-like ground motion. Based on nonlinear seismic analysis, fragility functions were developed to assess the damage states of buildings, where five types of structures are adopted to represent the most common buildings and infrastructures in Turkish cities. Furthermore, the spatial distributions of ground motion intensities and building damage states were validated using official damage reports and field surveys. Results indicate that our model aligns well with these reports and surveys, provided that sufficient seismic records are available. Extensive building damage in the earthquake is primarily attributed to the high intensities of strong motion, construction quality and building resonance, with additional contributions from earthquake-induced geological and geotechnical hazards. Moreover, near-fault regions experienced greater damage due to stronger pulse-like ground motions, fault displacements, and geohazards, all closely associated with fault ruptures. By providing insights into special seismic impacts in near-fault regions and the real characteristics of ground motions, this work contributes to the advancement of ground motion modeling, seismic risk analysis, and disaster management, ultimately supporting the development of more resilient communities.

Abstract：Gravity and magnetotelluric methods are pivotal geophysical techniques used to study the distribution of density and electrical conductivity within the Earth's interior. These methods have been widely used in multi-scale explorations for various engineering and academic applications. Considering the varying resolution capabilities of different geophysical methods in delineating near-surface geological structures, we propose a three-dimensional parallel joint inversion framework for gravity and MT data, based on Gramian structural constraints. The framework discretizes the inversion model with an unstructured tetrahedral mesh, enhancing the efficiency of forward modeling and sensitivity calculations for both gravity and MT data via a parallelized approach. To achieve sharper and more focused subsurface imaging, we incorporate a zero-order minimum entropy constraint into the objective function of the joint inversion. The objective function is minimized using the Gauss-Newton method, with model updates facilitated by the MINRES solver and line search techniques. Results from synthetic models show that joint inversion significantly improves the results for gravity and MT data, revealing a stronger correlation between residual density and resistivity. The zero-order minimum entropy constraint delivers more distinct model boundaries compared to traditional regularization method.

During space weather events, electric currents in the magnetosphere and ionosphere induce telluric currents near the Earth’s surface, which in turn generate disturbances of the local magnetic field that perturb the detection systems of broad-band sensors. Seismologist consider this effect as noise masking low frequency seismic waves. However, records of this interference can become an opportunity to study in greater detail the evolution of magnetic events and their effects on Earth.
The May 2024 solar storm, the largest in recent decades, has provided an excellent opportunity to analyze these signals. Thanks to their wide global distribution and their availability through platforms such as EPOS, broad-band seismometers provide extensive coverage of the magnetic signals associated with the solar storm. As an example, more than 310 seismometers have clearly recorded the solar storm in Europe, compared to the few tens of magnetometers available in the Intermagnet network in the same region. This geomagnetic storm has been recorded by broad-band seismometers distributed around the world for a time interval of more than 55 hours. Signals related to magnetic field variations can be identified in seismic data for frequencies below 10 mHz, but are clearer between 1.5 and 5 mHz, the frequency band corresponding to Pc5 magnetic pulsations. In the case of magnetic and seismic signals acquired at close locations, there is an excellent correlation between the seismic records and the time derivative of the magnetic field. The number of seismological stations that detect the signals varies significantly between the various seismic networks analyzed, depending on factors such as the presence of magnetic insulation systems or the bandwidth of the sensor.
Our study shows that the recording of magnetic events in broad-band seismometers can be affected by local effects that modify their amplitude and/or polarity, making a detailed calibration of each seismometer necessary before using seismic data to model the waveforms and amplitudes of the magnetic pulsations. However, broad-band data facilitate the monitoring of the temporal variations of the magnetic field disturbances in a large number of sites around the world, hence providing valuable information to complement data acquired by magnetometers.

A Jupyter Notebook devoted to a multiparametric investigation of the Amatrice-Norcia Italian seismic sequence 2016-2017Fri, 02 May, 14:00–15:45 (CEST) | vP2.11
Central Italy experienced a catastrophic seismic sequence that suddenly started on 24 August 2016 at 1:36:32 UTC with an Mw = 6.0 earthquake. Buildings damaged by the shaking of this event caused about 300 fatalities, and several towns (e.g., Amatrice, Accumuli, Arquata del Tronto) were destroyed entirely. A seismic sequence started from this event, and the largest event occurred more than two months later on 30 October 2016 at 6:40:17 UTC with magnitude Mw = 6.5. On 18 January 2017, a resurgent of the seismic sequence occurred with four events of magnitude equal to or greater than 5.0 in a Southern sector of the interested region (close to Capitignano/Montereale/Campotosto Lake). Then, the sequence followed a typical multi-year decay. The impact was huge, and from an energetic point of view, the event of 30 October 2016 was one of the largest recorded in the last 40 years in Italy.
Considering this particular case study, we developed a multidisciplinary and multiparametric Jupyter Notebook which can be run, e.g. in a Virtual Research Environment (VRE). The Open Source Code and friendly environment of Jupyter Notebook permit future users to adopt the same VRE to study other earthquakes.
The Jupyter Notebooks retrieves data mainly from the European Plate Observing System (EPOS) platform (Bailo et al., 2023, https://doi.org/10.1038/s41597-023-02697-9), integrating with other sources such as climatological archives and Swarm magnetic satellites of European Space Agency (ESA). EPOS is a European research infrastructure devoted to understanding plate tectonics through multidisciplinary and multiparametric studies. EPOS has already implemented a portal (https://www.epos-eu.org/dataportal, last accessed 10 January 2024) where users can retrieve data grouped into 10 disciplines (Thematic Core Services – TCS).
The Italian seismic sequence interests the extensional plate typical of the Central Apennine Mount Chain, and multiparametric data can help to understand the physical and chemical processes that could occur before and during the earthquake. The VRE relies on the results published by (Marchetti et al., 2019) but using updated algorithms such as the one used to study the Arabian Plate earthquake doublets (Ghamry et al., 2024, https://doi.org/10.3390/atmos15111318). We will also include other atmospheric investigations of specific parameters (e.g., Piscini et al., 2017, https://doi.org/10.1007/s00024-017-1597-8). Such previous studies propose evidence for anomalies in the organised chain of lithosphere, atmosphere, and ionosphere that were identified before the Italian seismic sequence 2016-2017.
These preliminary studies contribute to investigating the relations between geo-layers in our Earth’s system and the influence of seismic activity on them. Furthermore, this VRE adds a tool to the EPOS platform with potentially several applications, such as investigations of other significant earthquakes or other natural hazards, such as volcano eruptions.
