Just 9 minutes ago, a 3.6-magnitude earthquake struck near South Lake Tahoe, El Dorado County, California, USA. The tremor was recorded early evening on Wednesday, September 22nd, 2021, at 6:53 pm local time, at a very shallow depth of 4.1 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.3 earthquake.
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 Coleville (pop. 500) located 2 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Topaz Ranch Estates (pop. 1,500) located 13 miles from the epicenter, Smith Valley (pop. 1,600) 19 miles away, Smith (pop. 1000) 20 miles away, Gardnerville Ranchos (pop. 11,300) 27 miles away, Gardnerville (pop. 5,700) 31 miles away, Gardnerville (pop. 5,700) 31 miles away, and South Lake Tahoe (pop. 21,700) 38 miles away.
