Landslide mechanisms and processes in seismically or volcanically active environments
Convener: Randall W. Jibson  | Co-Conveners: Janusz Wasowski , Hiroshi Fukuoka , Chyi-Tyi Lee , Vincenzo Del Gaudio 

Earthquake shaking commonly triggers multiple hazards including landslides and other ground failures (e.g. liquefaction, subsidence, surface faulting). Recent events such as the 2008 M-7.9 Wenchuan (China) earthquake show that the death toll and destruction from seismically induced landslides can be extremely high. Similarly, volcanic earthquakes and volcanic activity in general commonly trigger damaging mass movements. Multiple hazards resulting from these different destabilizing forces are commonly treated separately, even though an integrated approach to the problem is clearly desirable. The purpose of this session is to provide a forum for discussion among researchers and other professionals who study landslides 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 earthquakes analyzed at both local and regional scales; b) case histories of mass movements induced by volcanic activity; c) assessments of landslide and other ground-failure hazards in relation to deterministic earthquake and volcanic event scenarios or to regional probabilistic evaluations; 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.
