Session ID#: 12890

Session Description:
Site amplification produced by local geological conditions plays a key role in seismic shaking hazard assessment and mapping. Although the topic has received significant attention over the past decades, a number of scientific and engineering issues are still unsatisfactorily answered and the latest data often raise new questions. This session will focus on improvements in the scientific understanding of site effects, and we invite contributions that include new observations, numerical modeling, and geophysical imaging of sedimentary basins and valleys. Of particular interest are studies in areas of high topographic relief, and we encourage discussion of the contrasting role of topography vs. material characteristics in amplification of ground motion. In addition, the session encourages discussion of innovative methods of site characterization besides Vs30, as well as contributions from diverse fields of application covering soil nonlinearity, slope instability, liquefaction, fault zone cracks, spatial variability of ground motion, and near surface attenuation.
