Sawtooth Fault

The Sawtooth Fault is an east-dipping normal fault (vertical motion) which runs along the eastern base of the Sawtooth Mountains in the state of Idaho in the United States.

In 2010, Glenn Thackray and colleagues from Idaho State University discovered the Sawtooth Fault near the base of the mountains using LIDAR. They found that it could produce an earthquake measuring up to magnitude 7.5 on the Richter scale and that two past large earthquakes likely took place on the fault around 7,000 and 4,000 years ago. The fault is 40 mi (64 km) long, and runs near Stanley, Idaho and Redfish Lake. Future earthquake could be felt as far as Boise.[1][2][3]
