Main Street in Challis, 2007
  • Main Street in Challis, 2007
Residents in the the central Idaho community of Challis are no strangers to earthquakes, and the most recent quake rumbled through the Custer County community on May 18.

The U.S. Geological Survey confirmed a 3.2 quake centered 4 miles east of Challis at 9:22 a.m. Monday. Later in the afternoon a 3.1 quake hit Yellowstone National Park, on the north end of Yellowstone Lake.  

In January, a 4.9 magnitude tremor shook Challis—the strongest in the area since 2005—and was felt as far away as Boise, Garden City and Mountain Home. The most powerful quake in Idaho history came in 1983 near Borah Peak, when a 6.9 earthquake
resulted in two deaths and caused $12.5 million in damage to the Challis-Mackay area.
