On December 30, 2025 at 23:57 UTC, a magnitude 2.0 earthquake struck 115 km N of Yakutat, Alaska. This event falls inside the aftershock decay of a nearby magnitude 3.3 earthquake that occurred about 2 hours earlier. At a depth of just 3.6 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 60.580°N, -139.900°E. The solution has been reviewed by a USGS seismologist and is considered finalized. See the M2.0 event page for the full report, ShakeMap, and citizen-reported intensity data.
