Seismic analytics

Analytics

Aggregations computed in ArangoDB over the stored catalogue. Counts reflect what QuakeWatch has ingested, not the complete global record.

Coverage note: historical backfill imports M2.5+ events; smaller events are present only from the start of live monitoring. Derived statistics (regions, latency) are QuakeWatch computations and are labelled as such.
