Several types of dangerous phenomena (either natural or man-made) pose a serious risk in many parts of the world. A fundamental task in hazard evaluation includes the prediction of the area influenced by the hazardous phenomenon, of its evolution in space and time, and the understanding of triggering mechanisms.
As concerns specific risk evaluation, a further issue must be analysed in terms of vulnerability.
Aiming at decreasing the risk, innovative approaches may range from modelling to monitoring, to landuse planning and knowledge dissemination, to realizing remedial works.
Studies describing innovative methods of monitoring, modelling and simulation (and related methods of calibration and validation, as well as of sensitivity analyses) are solicited. Comparative discussions on potential and limits of different approaches are also within the scope of this session.

As in the past years, after the conference Authors of studies presented (either as oral or poster) at the session will be invited to submit full papers for consideration of publication in a peer-reviewed special issue of an international journal.
For 2010, preliminary agreements have already been made with the Editorial Boards of "Natural Hazards" and "Earthzine".
