S001:
Earthquake hazards in areas affected by complex site response: the challenge of understanding the site behavior and the role of thick sediments





Session ID#: 29083

Session Description:
Seismic ground shaking depends on the seismic source, propagation path and, largely, on site response. Site effects are caused by multiple physical phenomena caused by the presence of stratigraphic discontinuities, soil layering, and surface or buried morphology. For instance, deep unconsolidated soils may present strong site response, which can amplify ground motion at some frequencies, but dampen motion at other frequencies. Such environments are also susceptible to extensive soil liquefaction. In addition, signs of active faulting are often suppressed or hidden by recent sedimentation, which leads to earthquake hazards not being recognized until after a significant event. Although site effects have been well studied over the previous decades, several scientific and engineering issues remain unsatisfactorily answered. Advances in this research field are fundamental to the improvement of anti-seismic codes for design, which often ignores complex, but critical site conditions. This session aims to explore all aspects of earthquake hazard research related to site effects (basin effects, topographic effects, soil nonlinearity, liquefaction, slope instability). We also invite studies from both recent earthquakes (e.g., Christchurch and Kaikoura, New Zealand; Emilia and Central Apennines, Italy) and historic events (e.g., Charleston, South Carolina; New Madrid, Missouri).
