On February 12, 2026 at 22:54 UTC, a magnitude 3.3 shallow crustal earthquake struck 1 km NNW of Point MacKenzie, Alaska, at a depth of 43.6 km and coordinates 61.3720°, -149.9840°. The earthquake was reported felt by 29 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 2.5 (weak). This earthquake was detected by 175 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 177, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 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.

Common Questions

How strong was the magnitude 3.3 earthquake near Point MacKenzie, Alaska?

The magnitude 3.3 earthquake that struck 1 km NNW of Point MacKenzie, Alaska on February 12, 2026 at 22:54 UTC had a depth of 43.6 km. It was felt by 29 people with maximum shaking intensity of MMI 2.5 (weak). For context, this was a minor earthquake typically detected only by instruments.

Where did the earthquake occur?

The earthquake epicenter was located at 61.3720°, -149.9840°, which is 1 km NNW of Point MacKenzie, Alaska. View all earthquakes in Alaska.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.3 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 3.3 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.
