An earthquake of magnitude 3.7 occurred around noon on Sunday, September 26th, 2021, at 12:23 pm local time near South Lake Tahoe, El Dorado County, California, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a very shallow depth of 2.2 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 3.7 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, 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) 19 miles away, Smith (pop. 1000) 20 miles away, Gardnerville Ranchos (pop. 11,300) 31 miles away, Gardnerville (pop. 5,700) 34 miles away, and South Lake Tahoe (pop. 21,700) 42 miles away.

Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
