Largest earthquake in nearly a year shakes up Idaho on Monday. Where was its epicenter?

CLAYTON (Idaho Statesman) — The largest earthquake the state has experienced in nearly a year shook Central Idaho on Monday morning.

The U.S. Geological Survey reported a magnitude-4.2 quake at 9:32 a.m., originating near Clayton in Custer County, according to the agency’s website. The reported location was 16 miles west-northwest of Clayton.

It occurred at a depth of about 7 miles, the USGS said.

The Custer County Sheriff’s Office told the Idaho Statesman that it received no immediate reports of injuries or damages.

Idaho has not seen an earthquake of that size since February 2024, when a magnitude-4.9 earthquake hit near Smiths Ferry, north of Boise.

The U.S. Geological Survey did not immediately return the Statesman’s request for more information.
