Earthquake catalogues

Event data comes from public seismic networks, principally the USGS Earthquake Hazards Program real-time feeds, which aggregate contributing networks worldwide. Magnitudes and locations are theirs; review and revision timelines are theirs too.

This website

The live counter and feed on the landing page read the USGS M 2.5+ past-day summary feed, refreshed every few minutes. When the feed is unreachable the page shows recent representative events instead.

Felt reports

Community intensity dots come from Seismoscope users and are shared back as anonymised, approximate locations.
