Earthquakes in Montana

Montana is one of the more seismically active interior states, with earthquakes concentrated in the mountainous southwest near the Intermountain Seismic Belt and Yellowstone. The 1959 Hebgen Lake quake was among the largest in Rocky Mountain history, and the region still produces felt events regularly.
