A preliminary 2.9-magnitude earthquake struck the East Bay overnight Monday, followed by a 3.0 at 5:21 a.m., according to the U.S. Geological Survey. The epicenters were 2.7 miles
Just after 8 a.m. Bay Area residents received a MyShake alert warning of magnitude 5.9 earthquake hitting east of Carson City, Nevada close to the Lake Tahoe region. The quake also appeared on the USGS map of latest earthquakes. But within minutes the report of the quake disappeared on the USGS page.
“On December 4, 2025, the ShakeAlert EEW system released an incorrect alert for a magnitude 5.9 earthquake near Reno and Carson City, Nevada,” the statement read. “The event did not occur, and has been deleted from USGS websites and data feeds. The USGS is working to understand the cause of the false alert.”
