The United States Geological Survey reported a magnitude 4.4 quake in the United States near South Lake Tahoe, El Dorado County, California, only 5 minutes ago. The earthquake hit in the afternoon on Thursday 8 July 2021 at 5:27 pm local time at a very shallow depth of 4 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.4 as well.
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 Walker (pop. 720) located 11 miles from the epicenter, Topaz Ranch Estates (pop. 1,500) 22 miles away, and Gardnerville Ranchos (pop. 11,300) 32 miles away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Gardnerville (pop. 5,700) located 35 miles from the epicenter, Gardnerville (pop. 5,700) 35 miles away, South Lake Tahoe (pop. 21,700) 39 miles away, Arnold (pop. 3,800) 40 miles away, and Carson City (pop. 54,500) 51 miles away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
