M3.4 Earthquake 2 km NE of Trapper Creek, Alaska — June 19, 2026
2026-06-19 00:16:43 UTC (2 hours ago) · approx. 2:16 PM UTC-10 local
Felt by 12 people across nearby locations.
On June 19, 2026 at 00:16 UTC, a magnitude 3.4 shallow crustal earthquake struck 2 km NE of Trapper Creek, Alaska, at a depth of 17.1 km and coordinates 62.3360°, -150.1980°. The earthquake was reported felt by 12 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.2 (light). This earthquake was detected by 51 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 182, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 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.

Where did the earthquake occur?
The earthquake epicenter was located at 62.3360°, -150.1980°, which is 2 km NE of Trapper Creek, Alaska. View all earthquakes in Alaska.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.4 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 3.4 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.
