Submarine landslides have become recognized as relatively common in all continental margins. Access to industry 3D seismic data and the new discipline of seismic geomorphology have also provided new lights on the architecture and processes of submarine slope failure and relationship to fluid flow in continental margins. Yet, because of lack of samples and direct observation, little is known of recurrence rates, trigger mechanisms, pre and post-failure geotechnical conditions and rheological properties during failure and the role of landslide processes in delivering sedimentary and associated organic matter from shallow to deep water. In addition, tsunami generation from submarine landslides is not yet fully understood. In line with IGCP585 objectives, we welcome contributions describing advances in submarine landslide investigations, including, but not limited to: bathymetric and 3D seismic geomorphology, sub-surface geophysical and geotechnical characterization, event dating and recurrence rates, deposit sedimentology, pre-conditioning/triggering analysis and numerical modeling of submarine landslide processes and landslide derived tsunamis.
