New Publication Maps More Than 22,000 Landslides in Utah

A new publication, recently released by the Utah Geological Survey shows more than 22,000 landslides, including debris flows that have occurred throughout the state. “Most landslides in Utah generally result from the reactivation of pre-existing landslides or hillslope modification of landslide-prone geologic units,” says Ashley Elliott, UGS Geologist. “If we understand the distribution of landslides and landslide-prone geologic units, we can reduce future landslide-related losses.”

The landslide maps can be used by local governments, developers, geotechnical consultants, the general public, and others interested in or concerned about landslides to identify potential landslide hazards and the need for site-specific geologic-hazard and geotechnical investigations in areas of proposed development.
