Submarine landslides present a significant hazard to communications cables, offshore energy development, and to coastal regions via the generation of tsunamis. One of the critical components of assessing hazards posed by submarine landslides is determining the probability of occurrence. For an empirical determination of probability, there are very few places in the world where a sequence of submarine landslides have been individually dated. However, in 2005, cores from two Integrated Ocean Drilling Project (IODP) sites in the Ursa Basin, northern Gulf of Mexico penetrated through a sequence of deposits left by landslides. This study develops a methodology to estimate the probability of submarine landslides from a sequence of dated deposits, such as those found in the Ursa Basin.
