The Utah Geological Society has released a detailed report about hazards in southern Utah.
The society reported that geological hazards, such as flooding and rock slides, are becoming a threat to the growing communities of La Verkin, Virgin, Rockville and Springdale.
This report comes after a rock slide in Rockville that killed a couple in December.
The report includes nine geologic-hazard maps that cover flooding and debris flows, rock fall, landslides, surface faulting, liquefaction, collapsible soil, expansive soil and rock, gypsiferous soil and rock, and soil piping, erosion, and wind-blown sand. Each map includes information on the nature and distribution of the hazard, how the maps were generated, and methods that may reduce the hazard.
