On January 1, 2026 at 06:46 UTC, a magnitude 5.7 shallow crustal earthquake struck 111 km N of Yakutat, Alaska, at a depth of 5.0 km and coordinates 60.5362°, -140.0494°. The earthquake was reported felt by 35 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.8 (very strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 516 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 513, placing it among routine seismic activity. The nearest populated place is Haines Junction (population 1,148).

Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 km — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in Alaska, a region characterized by Pacific Plate subduction beneath the North American Plate, producing frequent megathrust and crustal earthquakes along the Aleutian arc. The nearest mapped fault system is the Aleutian megathrust. View all earthquakes in Alaska.

Common Questions

How strong was the magnitude 5.7 earthquake near Yakutat, Alaska?

The magnitude 5.7 earthquake that struck 111 km N of Yakutat, Alaska on January 1, 2026 at 06:46 UTC had a depth of 5.0 km. It was felt by 35 people with maximum shaking intensity of MMI 6.8 (very strong). For context, this was a moderate earthquake that could be widely felt.

Where did the earthquake occur?

The earthquake epicenter was located at 60.5362°, -140.0494°, which is 111 km N of Yakutat, Alaska. The nearest populated place is Haines Junction (population 1,148). View all earthquakes in Alaska.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.7 earthquakes can continue for days to weeks and gradually diminish over time.

Has Alaska had earthquakes this big before?

The largest recorded earthquake in Alaska was the M9.2 Great Alaska earthquake of March 27, 1964. Today's magnitude 5.7 event is significantly smaller than that historical record.

What should I do after an earthquake?

If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
