SubMachine is a collection of web-based tools for the interactive visualisation, analysis, and quantitative comparison of global-scale datasets of the Earth's interior [1]. It focuses on making regional and global seismic tomography models easily accessible to the wider solid Earth community to facilitate collaborative exploration. Over 30 tomography models can be visualised and explored—individually, side-by-side, or through statistical and averaging tools. SubMachine also serves diverse non-tomographic datasets, including plate reconstruction models, normal mode observations, global crustal structure, shear wave splitting, geoid, marine gravity, vertical gravity gradients, and global topography in adjustable degrees of spherical harmonic resolution.
To ensure continuity beyond the DEEP TIME ERC project [2], SubMachine is transitioning to a new home within ORFEUS (Observatories and Research Facilities for European Seismology, http://orfeus-eu.org/). This transition secures SubMachine’s long-term sustainability and further integrates it into the broader seismological research infrastructure.
In preparation for this move, SubMachine has undergone significant modernization. The entire platform has been migrated to Python 3.12. The transition from Basemap to Cartopy enhances long-term stability, though some projections may experience slower performance. New features include cross-sections through vote maps [3]. These advancements, along with various performance improvements, position SubMachine as a more robust and sustainable resource for the geoscience community.
