A false earthquake alert in Nevada was quickly retracted due to a system glitch, with no quake or harm reported.

A false earthquake alert issued by the U.S. Geological Survey on December 4, 2025, reported a magnitude 5.9 quake near Dayton, Nevada, but was quickly retracted after no seismic activity was detected. The alert, sent via the ShakeAlert system, caused brief public concern, though residents reported no shaking and officials confirmed no earthquake occurred. The USGS attributed the error to a system glitch, with the Nevada Seismological Laboratory pointing to data issues in the alert system. No injuries or damage were reported, and the agency is investigating the incident, promising a future statement.
