Significant earthquake of magnitude 5.2 just reported 77 miles southeast of Chignik Lagoon, Alaska, United States

5.2 quake 2 Jun 1:41 pm (GMT -8)
5.2 quake 2 Jun 1:41 pm (GMT -8)
Just 9 minutes ago, a 5.2-magnitude earthquake struck near Chignik Lagoon, Lake and Peninsula, Alaska, USA. The tremor was recorded around noon on Thursday, June 2nd, 2022, at 1:41 pm local time, at a very shallow depth of 4.9 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 5.2 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 5.2.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Chignik Lagoon (pop. 78) located 77 miles from the epicenter.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
