Utah Offers New Hazard Maps for Salt Lake County

Utah is selling new maps that show the shaking intensity of earthquakes for the west half of Salt Lake County.

The set of 10 maps also spotlights the risks of landslides, rock falls, floods, radon gas and other hazards in the area.

The Utah State Geological Survey is selling a CD for $25 that contains a set of the maps and a 73-page report.

State geologists say the set will help guide development as population overtakes the west half of the Salt Lake basin.

The maps also spotlight the threat of collapsible or expansive soils, which can wreck buildings.
