USGS data fetched Nov 03, 2026, 18:45 UTC · page built Nov 03, 2026, 18:45 UTC. How to read this page: recent-window counts cover M1.5+ events within 100 km; the 10-year layer is based on M3.0+ and the history layer on M4.0+ since 1980. Recording completeness varies by era and region — small quakes from early decades are under-recorded, so “no record” does not prove “never happened”. Depths are relative to sea level and can be slightly negative for shallow events in elevated terrain. Method: data & methodology.
