Moderate magnitude 4.2 earthquake 63 miles south of False Pass, Alaska, United States

A magnitude 4.2 earthquake near False Pass, Aleutians East, Alaska, USA, was reported only 16 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 moderately shallow depth of 19 miles beneath the epicenter in the afternoon on Thursday, August 20th, 2026, at 4:14 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 4.2 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include False Pass (pop. 40) located 63 miles from the epicenter.
