3.1 quake 22 Apr 5:52 pm (GMT -8)

An earthquake of magnitude 3.1 occurred in the afternoon on Thursday 22 April 2021 at 5:52 pm local time near Anchorage, Alaska, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a moderately shallow depth of 21 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.1 earthquake 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 Big Lake (pop. 3,400, 3 miles away), Knik-Fairview (pop. 14,900, 13 miles away), Meadow Lakes (pop. 7,600, 16 miles away), Eagle River (pop. 24,800, 18 miles away), Eagle River (pop. 24,800, 18 miles away), Anchorage (pop. 298,700, 19 miles away), Wasilla (pop. 9,300, 19 miles away), Elmendorf Air Force Base (pop. 6,600, 20 miles away), and Tanaina (pop. 8,200, 21 miles away), the quake was probably not felt.
