Moderate magnitude 4.0 earthquake 28 miles northeast of Pedro Bay, Alaska, United States
4.0 quake 22 Mar 9:41 am (GMT -8)
4.0 quake 22 Mar 9:41 am (GMT -8)
An earthquake of magnitude 4.0 occurred only 6 minutes ago 28 miles northeast of Pedro Bay, Alaska, United States, the United States Geological Survey reported.
The quake hit at an intermediate depth of 74 miles beneath the epicenter near Pedro Bay, Lake and Peninsula, Alaska, USA, in the morning on Monday 22 March 2021 at 9:41 am 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.0 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 Pedro Bay (pop. 42, 28 miles away), and Anchor Point (pop. 1,900, 52 miles away), the quake was probably not felt.

If you did NOT feel the quake although you were in the area, please report it! Your contribution is valuable to earthquake science, seismic hazard analysis and mitigation efforts. You can use your device location or the map to indicate where you were during the earthquake. Thank you!

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.
