Idaho is crossed by the Intermountain Seismic Belt and by active Basin and Range faults. The 1983 Borah Peak earthquake (M6.9) is the strongest in the state's recorded history and ruptured the Lost River Fault, creating a scarp up to about 2.7 metres high. The 2020 Stanley earthquake (M6.5) was felt across several states. Major faults include the Lost River Fault, Lemhi Fault, Sawtooth Fault, and Beaverhead Fault. Notable quakes include the 1983 Borah Peak earthquake (M6.9) and the 2020 Stanley earthquake (M6.5). The seismic risk is moderate to high. Tectonically, Idaho lies in the northern Basin and Range province, where the crust is being pulled apart. This page provides real‑time USGS data and historical context for Idaho.

The region is defined by Lost River Fault, Lemhi Fault, Sawtooth Fault, Beaverhead Fault, and the risk level is classified as Moderate to High. With a population of 1.9 million, understanding local seismic hazards is crucial.
Idaho lies on Intraplate – Basin and Range extension (Intermountain Seismic Belt). The movement of these plates builds up stress, which is released as earthquakes. In subduction zones, one plate dives beneath another, generating some of the largest quakes on Earth. In some regions, strike‑slip faults produce frequent moderate earthquakes.

The strongest recorded earthquake in Idaho was the 1983 Borah Peak earthquake (M6.9). 1983 Borah Peak (M6.9)
Idaho experiences low to moderate seismic activity, with occasional felt earthquakes, according to USGS historical data.
The most recent major earthquake in Idaho was the 2020 Stanley earthquake (M6.5). 2020 Stanley (M6.5)
Yes. Idaho is crossed by Lost River Fault, Lemhi Fault, Sawtooth Fault, Beaverhead Fault, making it prone to seismic activity. The seismic risk level is classified as Moderate to High.
Drop, cover, and hold on. Stay away from windows, and if outdoors, move to an open area. After the shaking stops, check for injuries and be ready for aftershocks. Prepare an emergency kit with water, food, first aid, and a flashlight.
