Small magnitude 3.6 earthquake 51 miles northeast of Eagle River, Alaska, United States

A magnitude 3.6 earthquake near Eagle River, Anchorage, Alaska, USA, was reported only 5 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 6.2 miles beneath the epicenter in the morning on Thursday, August 20th, 2026, at 9:58 am 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.6 as well.
Weak shaking might have been felt in Chickaloon (pop. 270) located 20 miles from the epicenter.
