Depth: median 28.3 km, deepest 242.1 km. Median magnitude 2.00. Average per week over 30 days: 486.5. Tsunami flag set on 1 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: 2085 events in 30 days × 7 ÷ 30 = 486.5 per week on average; the last 7 days had 333.
USGS lists 2085 earthquakes of magnitude 1.5 or higher labeled Alaska in the 30 days before Oct 27, 2026, 23:38 UTC: 333 in the last 7 days and 31 in the last 24 hours. 518 of them reached M2.5 or higher and 183 reached M3.0 or higher.
The largest was M5.6, 43 km NNW of Lake Minchumina, Alaska, at Oct 15, 11:07 UTC, at a depth of 4 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 “Alaska”, 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 112 events have at least one felt report, 1239 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.
