Moderate earthquake of magnitude 4.1 just reported 55 miles northeast of Adak, Alaska, United States

4.1 quake 5 Aug 11:17 pm (GMT -9)
The United States Geological Survey reported a magnitude 4.1 quake in the United States near Adak, Aleutians West, Alaska, only 19 minutes ago. The earthquake hit late at night on Friday, August 5th, 2022, at 11:17 pm local time at an intermediate to considerable depth of 139 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 citizen-seismograph network of RaspberryShake, which listed it as a magnitude 4.1 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.1.
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, 55 miles away), the quake was probably not felt.

Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
