  Information - NH3.05 Landslides, ground-failures and mass movements induced by earthquakes and volcanic activity (co-listed in GM)

Event Information
Moderate to strong seismic shaking typically results in a series of hazards including landslides and other ground failures (e.g. liquefaction, subsidence, surface faulting). Similarly, volcanic earthquakes, and volcanic activity in general, often trigger damaging mass movements. Multiple hazards resulting from these different destabilizing forces are often treated separately, even though an integrated approach to the problem is clearly desirable. The purpose of this symposium is to provide a forum for discussion among researchers and other professionals involved in studies of landslides, ground failures, and related hazards caused by seismic and volcanic activity and to encourage multidisciplinary research in these fields. Among different possible topics, we would like to address the following: a) case histories of landslides triggered by recent and historic earthquakes, with analyses conducted both on local and regional scale; b) case histories of mass movements induced by volcanic phenomena; c) assessments of landslide and other ground failure hazards in relation to earthquake and volcanic event scenarios or to probabilistic evaluations on the basis of the general seismic, volcanic and tectonic setting and history of a given area, with the support of empirical or deterministic methods, as well as applying GIS techniques; d) studies regarding physical modelling of the influence of dynamic loading on slope stability and of seismically/volcanically induced landslide displacements; e) user requirements regarding hazard assessment and persisting challenges; (f) possible site effects such as amplification and influence of pre-existing landslide masses; and (g) possible regional differences in the factors associated with landslide occurrence.
