Chiniak, Alaska – A magnitude 3.1 earthquake struck 227 kilometers southeast of Chiniak on Monday evening, according to the U.S. Geological Survey.
The quake occurred at 5:05 p.m. UTC at a depth of 10 kilometers, based on preliminary data from the USGS National Earthquake Information Center. The event was marked as reviewed.
The epicenter was located offshore in the Gulf of Alaska, southeast of Kodiak Island. No immediate reports of damage or injuries were issued.
Earthquakes of this magnitude are typically considered minor and are often not felt, particularly when centered offshore. However, depth and distance from populated areas can influence whether shaking is noticed.
Chiniak is a small community on Kodiak Island, which sits within a seismically active region near the boundary of the Pacific and North American tectonic plates.
Residents can report shaking through the USGS “Did You Feel It?” system to assist researchers in assessing local impacts.
While this event was relatively small, Alaska experiences frequent seismic activity, making monitoring efforts ongoing.
