Depth: median 17.6 km, deepest 40.1 km. Median magnitude 1.81. Average per week over 30 days: 7.5. Tsunami flag set on 0 events (the USGS flag marks events in oceanic regions; it is not a tsunami warning, see tsunami.gov).
How the figures are counted: Events counted: USGS catalog type “earthquake”, magnitude 1.5 or higher, origin time in the 30 days before the data were pulled, location label ending in the state name or its postal abbreviation. Weeks are 7 × 24 hours counted back from the pull time.
Worked example: 32 events in 30 days × 7 ÷ 30 = 7.5 per week on average; the last 7 days had 5.
USGS lists 32 earthquakes of magnitude 1.5 or higher labeled Washington in the 30 days before Oct 27, 2026, 23:38 UTC: 5 in the last 7 days and 0 in the last 24 hours. 6 of them reached M2.5 or higher and 2 reached M3.0 or higher.
The largest was M4.2, 6 km WNW of Wauna, Washington, at Sep 29, 21:05 UTC, at a depth of 28 km.
Sites differ in the magnitude cut-off, the time window and how an event is assigned to a state. This page counts every event of M1.5 or higher in the USGS catalog whose location label ends in “Washington”, for the 30 days before the data were pulled. Small events are detected less completely in some areas, and magnitudes are often revised.
USGS collects felt reports through its “Did You Feel It?” system at earthquake.usgs.gov/data/dyfi. In this list 10 events have at least one felt report, 9741 reports in total.
This page is a statistics page, not a warning service. The official guidance from ready.gov is to Drop, Cover, and Hold On, and to follow instructions from local emergency officials.
