Earthquake and tremor catalogs for the 2025 Santorini seismo-volcanic crisis

This dataset contains the earthquake and tremor catalogs for the 2025 Santorini seismo-volcanic crisis described in Soubestre at al. (2026). The earthquake catalog is provided in tabular format using two files. The "events" file contains one earthquake per line. The "assignments" file describes the associated picks with one pick per line. To match the events and assignments, the columns "idx" in the events file and "event_idx" in the assignments file should be used. Column names for the events and picks use descriptive names. All times are provided in UTC. All coordinates use WGS84 as references. The tremor catalog is split into the swarm-related and deep-tremor clusters described in Soubestre et al. (2026). The tremor catalogs are provided in tabular format with self-descriptive column names.
