Akhiok, Alaska – A series of earthquakes struck southeast of Akhiok Sunday evening, including a magnitude 5.1 event that capped a short seismic sequence near Kodiak Island.
According to the Alaska Earthquake Center, three earthquakes were recorded between 11:36 a.m. and 11:47 a.m. Alaska Standard Time (2036–2047 UTC) on Monday. The strongest quake, measured at magnitude 4.2, occurred approximately 111 kilometers south-southeast of Akhiok at a depth of about 5 kilometers.
Two earlier earthquakes preceded the largest event. A magnitude 3.9 quake was detected about 121 kilometers south-southeast of Akhiok, followed roughly nine minutes later by a magnitude 4.0 earthquake about 114 kilometers from the community. All three earthquakes were shallow, increasing the likelihood they could be felt in nearby areas.
The Alaska Earthquake Center reported that the events were reviewed automatically and occurred offshore in the Kodiak Island region. As of Monday evening, no injuries, damage, or tsunami threats had been reported, and no tsunami warning was issued.
ShakeMap data for the magnitude 4.2 earthquake indicated light shaking near the epicenter, with limited impacts expected due to the offshore location and distance from population centers. No felt reports had been submitted at the time of publication, though residents are encouraged to share their experiences through the center’s online reporting system.
Southern Alaska is one of the most seismically active regions in North America, with frequent small to moderate earthquakes occurring along the boundary of the Pacific and North American tectonic plates. Clusters of earthquakes in the Kodiak Island area are not uncommon and are typically monitored for changes in activity.
For commuters, fishermen, and residents traveling coastal routes or working offshore, officials recommend staying informed through official earthquake updates.
The Alaska Earthquake Center continues to monitor the region for aftershocks or additional seismic activity.
