Stanley, ID – A minor earthquake shook parts of central Idaho early Thursday morning, with the U.S. Geological Survey (USGS) reporting a magnitude 3.2 tremor centered about 26 kilometers northwest of Stanley.
According to USGS data, the quake struck at 1:46 a.m. UTC (approximately 7:46 p.m. Wednesday local time) at a depth of 10 kilometers. The event was reviewed and confirmed by the USGS National Earthquake Information Center.
While only one “Did You Feel It?” report had been submitted as of Thursday morning, the quake occurred within a historically active seismic zone near the Sawtooth Fault—an area known for producing moderate quakes over the past decade.
No damage or injuries have been reported, and local authorities have not issued any alerts. Residents in the surrounding Custer County region may have experienced mild shaking, especially in elevated areas north of Stanley.
The Sawtooth Fault system has been under close observation since a magnitude 6.5 earthquake struck near the same area in March 2020, one of Idaho’s largest recorded quakes.
Experts say small to moderate tremors like Thursday’s are not uncommon in the region and serve as a reminder for residents to maintain earthquake readiness plans.
