“…Both natural and human activities, such as earthquake, gas hydrates dissociation [3,4], and hydrocarbon production [5], are able to trigger submarine landslides. As opposed to terrestrial landslides, submarine landslides normally affect a wider range of areas [6,7], not only posing a great risk to submarine pipelines and other seafloor structures [8,9] but also causing severe casualties due to tsunamis. Compared with forecasting the occurrence probability of a marine landslide, estimating the postfailure behaviors and characteristics of a marine landslide is of equal importance [10,11].…”
