4.9 quake 8 Jul 4:33 pm (GMT -7)
A very shallow magnitude 4.9 earthquake was reported in the afternoon near South Lake Tahoe, El Dorado County, California, USA.
According to the United States Geological Survey, the quake hit on Thursday 8 July 2021 at 4:33 pm local time at a very shallow depth of 5.8 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 4.9 earthquake as well.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Walker (pop. 720) located 4 miles from the epicenter, and Topaz Ranch Estates (pop. 1,500) 17 miles away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Smith Valley (pop. 1,600) located 23 miles from the epicenter, Gardnerville Ranchos (pop. 11,300) 30 miles away, Gardnerville (pop. 5,700) 33 miles away, Gardnerville (pop. 5,700) 33 miles away, South Lake Tahoe (pop. 21,700) 39 miles away, and Johnson Lane (pop. 6,500) 40 miles away.
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.
