Alaska earthquake activity at a glance
What the last 30 days look like in Alaska
128 earthquakes of magnitude 3.0 or above were recorded in the last 7 days, up from 25 the week before. In the last 24 hours: 4.
The largest was M6.3 on September 3, 84 km SSW of Nikolski, Alaska, 35.0 km deep, and 3 people reported feeling it.
The most widely felt was not the largest: M5.6, 57 km WNW of Skwentna, Alaska, with 1,137 reports.
Much of that activity is clustered: 83 events within 15 km of 97 km SSW of Nikolski, Alaska. A group like that is called an earthquake swarm; swarms are common and do not mean a larger earthquake is coming.

Frequently asked questions
Was there an earthquake in Alaska today?
Yes — 4 earthquakes of magnitude 3.0 or above were recorded in the last 24 hours. The list on this page is rebuilt every 30 minutes, newest first.
How many earthquakes does Alaska get?
218 of magnitude 3.0 or above in the last 30 days, 128 of them in the last 7. Most are too small to feel; that is normal for a seismically active region.
What was the biggest recent earthquake in Alaska?
Magnitude 6.3 on September 3, 2026, 84 km SSW of Nikolski, Alaska, at a depth of 35.0 km. 3 people reported feeling it.
How deep are earthquakes in Alaska?
In the last 30 days they ranged from 0.1 km to 216.7 km deep. Shallow earthquakes are felt more strongly near the epicentre; deep ones are felt weakly over a wider area.
How can I get earthquake alerts for Alaska?
Install the free SeismoWatch Android app, draw a box over Alaska, set a minimum magnitude, and turn alerts on. Alerts are sent after an event is published, so they are not an early warning.
Where does this data come from?
From the U.S. Geological Survey (USGS) global catalog, deduplicated. Each event links to its own page with the full record.
The strongest earthquakes recorded in Alaska since 1960
The 10 largest events of magnitude 6.0 or above in the Alaska monitoring area, from the USGS catalog. Recent activity is best read against this: a region's ordinary weeks look very different from its worst days.

Coverage and data notes
Events are preliminary, so magnitudes and locations may be revised. This page uses a rectangular monitoring area around Alaska, so border areas and nearby offshore zones can include events outside the administrative boundary. Completeness varies: a national network usually records more small earthquakes than the catalogs used here, so treat the counts as a floor rather than a census.
Event data: U.S. Geological Survey (USGS), the European-Mediterranean Seismological Centre (EMSC) and, in Venezuela, FUNVISIS. Populated places and time zones: GeoNames (CC BY 4.0). Preliminary solutions are revised as more observations arrive.
