A magnitude 3.7 earthquake near Nikolski, Aleutians West, Alaska, USA, was reported only 27 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 25 miles beneath the epicenter early morning on Tuesday, December 21st, 2021, at 5:59 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.7 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Nikolski (pop. 18) located 35 miles from the epicenter.
