The map shows quakes of M1.5 and up from the last 90 days, the 8 biggest on record, and always the very latest quake — even if it was smaller than M1.5. The list below can include smaller ones the map leaves out. Tap any dot for details.
In the last 30 days, 48 earthquakes of M1.5 or bigger were recorded within 100 km of Unalaska, the biggest of them M4.3. Over the past year, M3.0+ quakes near Unalaska came at 1.0× the usual pace — quieter than normal for this area. The biggest quake on record near Unalaska — records go back to 1980 — was the M6.9 of Feb 27, 1987, 08:31 UTC: 67 km SW of Unalaska, Alaska.
How we figure this: 70 quakes of M3.0 or bigger within 100 km in the last 12 months (Nov 03, 2025 – Nov 03, 2026), compared with an average of 71.1 a year across the full calendar years 2016–2025, counted the same way. This compares how often quakes happened in two past periods. It is not a forecast, and it does not mean a big earthquake is on its way — nobody can predict earthquakes.

USGS data fetched Nov 03, 2026, 15:45 UTC · page built Nov 03, 2026, 15:45 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.
