A magnitude 3.0 earthquake near South Lake Tahoe, El Dorado County, California, USA, was reported only 28 minutes ago by the United States Geological Survey, considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a very shallow depth of 4.4 miles beneath the epicenter early afternoon on Thursday 8 July 2021 at 3:58 pm local time. 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 4.2.
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. In Smith Valley (pop. 1,600, 20 miles away), Smith (pop. 1000, 21 miles away), Gardnerville Ranchos (pop. 11,300, 26 miles away), Gardnerville (pop. 5,700, 30 miles away), Gardnerville (pop. 5,700, 30 miles away), and South Lake Tahoe (pop. 21,700, 36 miles away), the quake was probably not felt.
