BOISE, Idaho — New research is shaking up what we know about Idaho earthquakes.
The magnitude-6.5 quake that rattled Southern Idaho in March 2020 has been attributed to the Sawtooth Fault in Central Idaho. But a paper published earlier this year in the Seismic Record said researchers now see no direct link between the two.
In fact, seismologists said in the paper, the quake near Stanley and its thousands of aftershocks could be linked to a previously undiscovered fault. Glenn Thackray, an Idaho State University seismologist who co-authored the recent paper, said the newly identified fault is near the Cape Horn and Banner Summit area along Idaho Highway 21.
