Small 3.5 quake hits near South Lake Tahoe, El Dorado County, California, USA

3.5 quake 8 Jul 4:13 pm (GMT -7)
3.5 quake 8 Jul 4:13 pm (GMT -7)
The United States Geological Survey reported a magnitude 3.5 quake in the United States near South Lake Tahoe, El Dorado County, California, only 7 minutes ago. The earthquake hit in the afternoon on Thursday 8 July 2021 at 4:13 pm local time at a very shallow depth of 1.1 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 3.5 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 2 miles from the epicenter, the quake should have been felt as light shaking.
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 16 miles from the epicenter, Smith Valley (pop. 1,600) 21 miles away, Smith (pop. 1000) 23 miles away, Gardnerville Ranchos (pop. 11,300) 29 miles away, Gardnerville (pop. 5,700) 33 miles away, and Gardnerville (pop. 5,700) 33 miles away. In South Lake Tahoe (pop. 21,700, 39 miles away), the quake was probably not felt.
