Workshop Report: Applications of Precarious Rocks and Related Fragile Geological Features to U.S. National Hazard Maps

The Workshop on the Applications of Precarious Rocks and Related Fragile Geological Features to U.S. National Hazard Maps met on the University of Nevada campus in Reno (UNR), Nevada, on 4–5 October 2010. The goal of this workshop was to develop recommendations to the U.S. Geological Survey (USGS) on the use of precariously balanced rocks and related fragile geological features to improve the national seismic hazard maps (NSHM). The context of the workshop is the growing realization that it is essential to regard hazard maps as the calculated output of hazard models that should be tested, and that fragile geological...
