Landslides

The USGS and its cooperators have installed instruments in a steep hillside about 17.5 km southwest of Franklin, NC in the Nantahala National Forest.

The USGS and its cooperators have installed instruments in a steep hillside about 16 km southeast of Otto, NC in the Coweeta Experimental Forest.

The USGS and its cooperators have installed instruments in a steep hillside about 38.5 km south of Asheville, NC in the Bent Creek Experimental Forest.

The Highway 50 landslide monitoring system uses data acquisition systems and radio telemetry developed by the USGS Volcano Hazards Program to operate in remote, hazardous sites with limited power. In many landslides, infiltration of rainfall or rapid snowmelt increases groundwater pressures. These elevated pressures can, in turn, trigger landslide movement.

In 2009, the Station Fire burned 160,000 acres in the San Gabriel Mountains. Vegetation has started to return, but it can take many years for a basin to fully recover from the effects of fire.

Release Date: MAY 15, 2018 The deadliest individual landslides in the U.S. recently were in places where there had previously been a landslide. Why do landslides happen in the same place instead of on nearby slopes that appear to be just as likely, if not more likely, to slide?

What persuades someone to heed a debris flow or wildfire evacuation warning? SAFRR partners in emergency management are especially interested in the results of this study, now underway with Columbia's Center for Research on Environmental Decisions.
