3.1 quake 17 Aug 1:38 am (GMT -8)
Just 10 minutes ago, a 3.1-magnitude earthquake struck near Sand Point, Aleutians East, Alaska, USA. The tremor was recorded early morning on Wednesday, August 17th, 2022, at 1:38 am local time, at an intermediate depth of 55 miles below the surface.
The event was filed by the United States Geological Survey, the first seismological agency to report it.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 3.1 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.1.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Perryville (pop. 110, 21 miles away), and Sand Point (pop. 1,100, 48 miles away), the quake was probably not felt.
