GBR Landslides

Undersea, or submarine, landslides are common features on steep continental margins and the sides of oceanic islands around the world. Submarine slope failure is a natural hazard process that dramatically shapes the seafloor environment and transfers large quantities of sediment from the shelf into the deep basins. In 2007, while on an expedition on the RV Southern Surveyor, we first discovered and mapped a series of underwater landslides along the Great Barrier Reef margin.

These images come from our work studying the landslides and their potential tsunamis.
