Session Description | Submarine landslides are controlled by long-term geological preconditioning factors (e.g. depositional environments, geotechnical properties of sediments, mass movement history and long-term climate change) and short-term triggering mechanisms (e.g. slope oversteepening, seismic loading, storm-wave loading, gas hydrate dissociation, gas charging, seepage, glacial loading and volcanic island processes). It can devastate offshore infrastructures and, moreover, induce tsunamis which caused widespread damages and numerous fatalities in coastal communities. Thus, understanding the geological constraints and triggering mechanisms of submarine landslides are of the highest priorities on submarine geohazard mitigation. The acquisition of dense and accurate submarine information using different geophysical, sedimentological, and engineering approaches has opened up new possibilities for improving our understanding of submarine geohazard and potential seafloor instability. This session hence welcomes contributions from different disciplines of earth sciences and we expected to have a general concept about the progress already carried out by the related research and to stimulate more multidisciplinary researches on the submarine geohazard and seafloor instability related issues. |
