Station Explorer: the new interactive EIDA web tool for seismic data discovery

The European Integrated Data Archive (EIDA) is a federation of 13 data centres dedicated to securely archiving seismic waveform data and providing seamless access to over 30,000 stations. For the past decade, EIDA’s holdings have been accessed through the WebDC3 interface. We are now replacing WebDC3 with a modern web application, "Station Explorer*," to address evolving requirements for interactive data discovery and secure, federated access.

Station Explorer provides unified access to data across all 13 federated data centres. Built with JavaScript and the Vue 3 framework, the interface features a modular architecture supporting both station-based and event-based workflows. Users can filter stations by time, network, region or distance/azimuth, while events can be refined by parameters such as time, region, magnitude, and depth. Data quality metrics from WFCatalog are visualised through interactive charts.

Authentication and Authorization Infrastructure (AAI) integration now supports both OAuth2 authentication flows and token-file uploads, enabling secure access to restricted data. To foster correct attribution practices, the interface now explicitly displays DOI information for networks and presents citation requirements within the download workflow. We also optimised performance through worker pools and parallel fetching to ensure a responsive user experience, implementing an 8-worker pool for details panel metrics and Web Workers for large inventory processing.

In this presentation, we will demonstrate the current implementation and new authentication workflows via a live demo including also power spectral density (PSD) visualization in the details view which is planned for integration as soon as rolled out throughout all EIDA nodes.
