Residents near the Teton County community of Driggs felt a minor earthquake Aug. 20.
The U.S. Geological Survey confirmed
that a 3.8-magnitude earthquake rumbled an area about eleven miles northeast of Driggs and 45 miles east of Rexburg. No injuries were reported.
The last significant earthquake in the region was last April when a 4.9 quake
rumbled Challis, the strongest in that area since 2005.
The most powerful quake in Idaho history came in 1983 near Borah Peak, when a 6.9 earthquake resulted in $12.5 million in damage to the Challis-Mackay area and resulted in two deaths.
