The Teton region is part of the Intermountain Seismic Belt, a region of relatively high seismicity in the Intermountain West that extends from northern Arizona to western Montana.  Most of the seismicity in the Teton region occurs east of Grand Teton National Park in the Gros Ventre range while there is very little earthquake activity on the Teton Fault.
