M3.7 Earthquake 0 km NW of Meadow Lakes, Alaska — March 11, 2026
2026-03-11 20:04:19 UTC (2026-03-11) · approx. 10:04 AM UTC-10 local
Felt by 221 people across surrounding communities.
On March 11, 2026 at 20:04 UTC, a magnitude 3.7 shallow crustal earthquake struck 0 km NW of Meadow Lakes, Alaska, at a depth of 27.2 km and coordinates 61.6300°, -149.6090°. The earthquake was reported felt by 221 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.5 (light). This earthquake was detected by 184 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 286, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — 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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.7 earthquakes can continue for several days 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 3.7 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.
