Small magnitude 3.7 quake hits 13 miles south of Larsen Bay, Alaska, United States around noon

A magnitude 3.7 earthquake near Larsen Bay, Kodiak Island, Alaska, USA, was reported only 4 minutes ago by the United States Geological Survey, considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a very shallow depth of 0.4 miles beneath the epicenter around noon on Tuesday, March 24th, 2026, at 1:04 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.2 earthquake. A third agency, The Incorporated Research Institutions for Seismology (IRIS), reported the same quake at magnitude 3.7.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Larsen Bay (pop. 88) located 13 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Karluk (pop. 37) located 22 miles from the epicenter, Akhiok (pop. 72) 29 miles away, and Old Harbor (pop. 220) 29 miles away. In Womens Bay (pop. 720, 55 miles away), and Port Lions (pop. 200, 55 miles away), the quake was probably not felt.
