Geological and seismological studies show that earthquakes are likely to happen in any of several active zones in Idaho and adjacent states.
On March 31, 2020 the Stanley earthquake
(M6.5) occurred approximately 19 miles northwest of Stanley, Idaho. The earthquake triggered a significant liquefaction event at Stanley Lake.
Idaho has also experienced two large earthquakes in historical times: the 1959 Hebgen Lake earthquake (M7.3) and the 1983 Borah Peak earthquake (M6.9).
