Landslides and other types of ground failure (e.g., liquefaction and subsidence) are among the most damaging effects triggered by earthquake shaking. Observations from several recent earthquakes have shown that the death toll and destruction from seismically induced landslides can be extremely high. Similarly, volcanic activity and related seismicity commonly trigger damaging mass movements. The multiple hazards resulting from these processes commonly are treated separately even though an integrated approach to the problem clearly is 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. Topics of interest include the following:
(a) case histories of earthquake-triggered landslides, analysed at either local or regional scale;
(b) site effects such as amplification and the influence of pre-existing landslide masses;
(d) analysis of factors associated with seismically/volcanically-induced landslide occurrence;
(b) slope stability and runout modelling of seismically/volcanically-induced landslide;
(e) assessments of landslide and other ground-failure hazards in relation to deterministic earthquake and volcanic event scenarios or to regional probabilistic evaluations;
(d) application of GIS techniques to evaluate and portray seismic and volcanic ground-failure hazards and risks;
(h) user requirements regarding risk assessment and persisting challenges.

A focused special issue in an EGU-journal will be edited based on the contributions of this session.
