A magnitude 3.7 earthquake near Port Alsworth, Lake and Peninsula, Alaska, USA, was reported only 12 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 an intermediate to considerable depth of 112 miles beneath the epicenter early evening on Thursday 5 August 2021 at 7:36 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.
