Abstract
Submarine landslides are becoming recognized as a potential source of damaging local tsunamis. However, there are presently few documented case studies of landslide events that have caused historic tsunamis or likely caused prehistoric tsunamis. We present three case studies of submarine landslide environments off the west coast of the United States, including Alaska. Each environment has been imaged using multibeam technology allowing excellent resolution of the morphology of the seafloor. Based on this imagery and the historic record, we document the character of these environments and the resulting tsunamis. In the case of one of the failures, we present a model of the motion of the landslide and the size of tsunami that this motion would have produced.
