3.9 quake 30 Apr 6:15 am (GMT -9)

The United States Geological Survey reported a magnitude 3.9 quake in the United States near Adak, Aleutians West, Alaska, only 21 minutes ago. The earthquake hit early morning on Friday 30 April 2021 at 6:15 am local time at an intermediate to considerable depth of 99 miles. 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 3.9 as well.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Adak (pop. 330, 32 miles away), the quake was probably not felt.
