Opis

Submarine mass movements and their consequences are of major concern for coastal communities and infrastructures but also for the exploitation and the development of seafloor resources. A tragic example of the vulnerability of coastal communities has been provided by the Indonesian tsunami of December 2004. Since 2005, as part of the scientific community efforts to minimize the impact of such natural disasters, the International Union of Geological Science (IUGS) and the United Nation, Educational, Scientific, and Cultural Organization (UNESCO) have sponsored an International Geoscience Program on Submarine Mass Movements and Their Consequences (IGCP-511). One of the main objectives of IGCP-511 members is to hold bi-annual symposia on these types of marine and coastal geohazards. The first symposium of this series was held in Nice (2003) and the second in Oslo (2005). This 3rd Symposium on submarine Mass Movements and Their consequences provides an opportunity to review the state of the art in risk evaluation from submarine landslides, deposit characterization and its implication for coastal and offshore development. By bringing together professionals from the industry and academia with a range of different expertise, these proceedings hope to cover the full spectrum of aspects related to subaqueous mass movements and related consequences. The interdisciplinary views gathered in this book, arising from the conference, help identify future challenges, mitigation strategies and better management of the seafloor. To that effect, the Santorini is quite a unique venue for scientists and engineers interested in marine and coastal geohazards.

Blurb

This book provides a world-wide perspective of submarine mass movements and their consequences. This has been made possible by assembling excellent contributions from active researchers, groups, or institutions, thus providing full coverage of the many scientific and engineering aspects of this type of marine and coastal geo-hazard. It covers fundamental as well as site specific studies from many areas including the Atlantic and Pacific Oceans, inner seas such as the Mediterranean Sea, and fjords using the most recent technologies from multibeam sonar imaging techniques, 3D seismic analysis, slope stability analysis, to debris flow and tsunami modeling.
Audience
This book is of interest to any researcher in the field of marine and coastal geo-hazards. It will be useful for planners, scientists and engineers involved in the development of offshore and near-shore resources and also to those in charge of the management and mitigation of coastal hazards. For graduate students, this book provides an up-to-date vision of the process of submarine mass movements and their consequences from both a scientific and an engineering standpoint, and it includes a unique collection of the existing literature on marine geo-hazards.
