Data
Every file below is rebuilt each time the collector runs (every 30 minutes). Times are UTC. One row is one earthquake after merging reports from USGS and EMSC (and IRSC for earlier events).

Full database
The complete DuckDB file: raw reports from each source (raw_events), merged events (events) and the collector log (source_runs).
Available once the scheduled collector has published it.
