Earthquakes that rupture the ground surface leave behind the telltale signature of fault scarps, which provide clues about seismic activity in the geologic past. A new study focused on scarps along the East Gallatin-Reese Creek fault system will provide more information on seismic hazards in northwest Yellowstone National Park.
Studying earthquakes and their associated hazards is an important part of the Yellowstone Volcano Observatory's mission. Earthquakes are among Yellowstone's geologic hazards most likely to occur over human timescales, and famous (and not-so-famous) strong earthquakes ha...
