Abstract:

Seismic risk for spatially distributed infrastructure is driven mainly by ground failure, defined as permanent ground displacements from mechanisms such as landslides, liquefaction, and seismic compression. Most forms of ground failure are a consequence of soil responses to ground shaking, which should be evaluated on a hazard-consistent scenario basis to represent spatial correlations of intensity measures. A companion report describes a methodology for identifying hazard-consistent event scenarios.
