Virtually no data on the Teton Fault has been recorded by the sensor network - yet. According to a University of Utah report, the Teton Fault is capable of producing magnitude 7.2 to 7.3 earthquakes.

JACKSON, Wyo. — Nearly 90,000 acres burned in the Bridger-Teton National Forest last year, and officials say most of the acreage charred was burned in fires started by humans.

Upward slippage of the fault’s western edge has pushed the mountains to their present height of some 7,000 feet (2,130 meters) above Jackson Hole in Grand Teton National Park.

Research shows the Teton fault last ruptured more than 5,000 years ago. Whether the fault is overdue for a big quake is unknown, geologists said Friday. Earthquakes are common in the region.
