A global compilation of fluid-based pre-seismic anomalies

This dataset represent a compilation of more than 900 fluid-related pre-seismic anomalies reported in crustal (non-volcanic) environments across 28 different countries between 1978 and 2025. The dataset integrates observations drawn from over 300 time-series and ~160 scientific publications, encompassing gas-geochemical, hydrogeochemical and physical parameters.
