Landslides are ubiquitous but largely underestimated hazards, primarily because they are often secondary in character and resulting death and damage is allocated to the primary event. In most cases this is either an earthquake, wherein landslides are generated due to strong ground motion, or severe precipitation, which results in mudslides. Landslide interest at the ABUHRC is focused primarily on the lateral collapse of ocean-island volcanoes and resulting tsunamis and on developing an improved understanding of the large volume, long-runout landslides known as Stürzstroms.
