The United States Geological Survey reported a magnitude 4.0 quake in the United States near South Lake Tahoe, El Dorado County, California, only 12 minutes ago. The earthquake hit in the evening on Thursday, March 17th, 2022, at 9:51 pm local time at a very shallow depth of 1.2 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 4.0 as well. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 4.0.
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 3 miles from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Topaz Ranch Estates (pop. 1,500) located 15 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Smith Valley (pop. 1,600) located 21 miles from the epicenter, Gardnerville Ranchos (pop. 11,300) 28 miles away, Gardnerville (pop. 5,700) 31 miles away, Gardnerville (pop. 5,700) 31 miles away, South Lake Tahoe (pop. 21,700) 37 miles away, and Johnson Lane (pop. 6,500) 38 miles away.

If you felt this quake (or if you were near the epicenter), please share your experience and submit a short "I felt it" report! Other users would love to hear about it!
If you did NOT feel the quake although you were in the area, please report it! Your contribution is valuable to earthquake science, seismic hazard analysis and mitigation efforts. You can use your device location or the map to indicate where you were during the earthquake. Thank you!

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.
