3.9 quake 13 Km NNW of Stanley, Idaho, USA, 15 Nov 1.48 pm (GMT -7)
Just 12 minutes ago, a 3.9-magnitude earthquake struck near the town of Challis, Idaho. The tremor was recorded around noon on Sunday 15 November 2020 at 1.48 pm local time, at a shallow depth of 9.1 miles below the surface.
The event was filed by the United States Geological Survey (USGS), the first seismological agency to report it.
Our monitoring service at VolcanoDiscovery identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.9 as well.
Despite its relatively small magnitude, the quake could probably be felt very close to the epicenter. Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Challis (pop. 1000) located 40 miles from the epicenter.
If you were or still are in this area during the quake help others with your feedback and file a quick report here.
