2025-12-29 2025-12-29 23:50:56 UTC	2.2ml	97 km N of Yakutat, Alaska 60.415°, -139.508°	1.0 km	-	-	-	✓ Reviewed	USGS →
The USGS recorded this magnitude 2.2 earthquake 97 km N of Yakutat, Alaska at 23:50 UTC on December 29, 2025. This event falls inside the aftershock decay of a nearby magnitude 2.3 earthquake that occurred about 9 hours earlier. At a depth of just 1.0 km, this was a very shallow event, close enough to the surface that modest magnitudes can produce significant local shaking. The event was offshore — common for earthquakes along subduction zones and transform plate boundaries. Geolocation places the event at 60.415°N, -139.508°E. The solution has been reviewed by a USGS seismologist and is considered finalized. See the M2.2 event page for the full report, ShakeMap, and citizen-reported intensity data.
