The map shows quakes of M1.5 and up from the last 90 days, the 4 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, 5 earthquakes of M1.5 or bigger were recorded within 100 km of Okanogan, the biggest of them M2.5. Over the past year, M3.0+ quakes near Okanogan came at 0.9× the usual pace — quieter than normal for this area. The biggest quake on record near Okanogan — records go back to 1980 — was the M4.6 of Nov 18, 2011, 13:09 UTC: 8 km WSW of Riverside, Washington.
How we figure this: 1 quakes of M3.0 or bigger within 100 km in the last 12 months (Nov 04, 2025 – Nov 04, 2026), compared with an average of 1.1 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.

These may be felt, depending on how far away and how deep they are. 2026 is not a full year yet — it only counts up to today. Source: USGS Earthquake Catalog.

USGS data fetched Nov 04, 2026, 02:24 UTC · page built Nov 04, 2026, 02:24 UTC. How to read this page: recent-window counts cover M1.5+ events within 100 km, measured from the center of the place, not the city limits; 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.
