3.7 quake 16 Aug 2:59 pm (GMT -11)
3.7 quake 16 Aug 2:59 pm (GMT -11)
A magnitude 3.7 earthquake near Nikolski, Aleutians West, Alaska, USA, was reported 37 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 shallow depth of 19 miles beneath the epicenter early afternoon on Tuesday, August 16th, 2022, at 2:59 pm local time. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
Our monitoring service identified a second report from the citizen-seismograph network of RaspberryShake which listed the quake at magnitude 3.7 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.7.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Nikolski (pop. 18) located 32 miles from the epicenter.
