[H-DS15] [EJ] Submarine landslides and their consequences

Tue. May 23, 2017 3:30 PM - 5:00 PM Poster Hall (International Exhibition Hall HALL7)

By recent high-resolution marine surveys, a lot of submarine landslides and their aspects have become recognized all around the world. Accordingly, submarine landslides also came to be known as a factor which may directly or indirectly affect our lives, causing tsunami or coastal erosion, cuts of submarine communication cables or pipelines, destruction of marine constructs, etc. Submarine landslide studies are strongly propelled by two International Geological Correlation Programmes (IGCP-511; 2005-2009 and IGCP-585; 2010-2014). International Ocean Discovery Program (IODP, former Integrated Ocean Drilling Program) raised submarine landslide as one of the important geo-hazard topics in new phase (2013-2023). However, generation factor and flow style of submarine landslides are very various, and have not been systematically sorted out yet. This session welcomes all scientists, researchers and engineers who investigate submarine landslides in the ocean, or ancient slide deposits on land, and who deal with model experiments or numerical simulations as well.
