Earthquake potential of the Wasatch Fault in Utah

Abstract

The majority of Utah’s population lives along the Wasatch fault, an active intraplate normal fault that extends for approximately 230 miles along the western front of the Wasatch Range. Investigations of earthquake recurrence on the Wasatch fault have revealed that segments of the fault have been the source of repeated large earthquakes, probably of magnitude 6-3/4 to 7-1/2 .
