Central and eastern Idaho are part of the Intermountain Seismic Belt. The 1983 Borah Peak earthquake (M6.9) is the largest recorded in the state and produced a surface rupture about 34 km long.
The M6.5 Stanley earthquake of March 2020 in the Sawtooth Range was the second largest recorded in Idaho, followed by a long aftershock sequence.

Where can I get official earthquake information for Idaho?
For official information, warnings and safety advice, follow Idaho Geological Survey (https://www.idahogeology.org/) and your local civil protection authority. This site compiles agency reports and is not a warning service.
How are earthquakes assigned to Idaho on this page?
An earthquake is listed in Idaho when the nearest town to its epicentre, within 200 km, is in the state. Earthquakes farther offshore are not included. Counts of magnitude 2.5 and above are comparable between states; smaller earthquakes depend on how dense the local seismic network is.
Can earthquakes be predicted?
No. Scientists can estimate how likely strong shaking is in a region over years or decades, but no method predicts the time, place and size of a specific earthquake. Aftershocks are expected after large earthquakes and become less frequent over time.
