S31B:
Earthquake Hazards in Areas Affected by Complex Site Response: The Challenge of Understanding the Site Behavior and the Role of Thick Sediments III Posters

Submit an Abstract to this Session



Session ID#: 29083

Session Description:
Seismic ground shaking depends on the seismic source, propagation path and 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. 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 invite studies from both recent earthquakes and historic events.
