Pedro Bay, Alaska – A small but deep earthquake shook a remote section of southwest Alaska on Sunday afternoon, registering a magnitude 3.1 roughly 55 kilometers east-southeast of Pedro Bay. While no damage was reported, the tremor added to ongoing seismic activity across the region.
According to the U.S. Geological Survey, the quake struck at 7:28 a.m. Alaska time at a depth of about 112 kilometers. The event was automatically reviewed, and no felt reports had been submitted as of Sunday evening. Deep quakes of this type are common in Alaska’s subduction zones and are typically less likely to cause surface damage.
Communities around Lake Iliamna, including Pedro Bay and nearby villages, may have experienced light shaking, though none has been confirmed. The location sits within one of the most seismically active regions in the world, where hundreds of small quakes occur each week. Emergency managers note that even minor earthquakes serve as reminders for residents to secure heavy items, review communication plans, and keep emergency kits accessible.
Alaska authorities will continue monitoring the area for aftershocks or additional seismic movement, though none are expected to be strong. Any updated information will be issued if notable activity develops.
