Study examines link between underwater landslides and tsunamis
Scientists have calculated a way to determine the speed of past underwater landslides, a new study has found.
Researchers from The Ohio State University studied the remains of an underwater landslide just off the coast of Oregon – dubbed the 44-N Slide – that is part of the Cascadia Subduction Zone (CSZ).
Stretching from Vancouver Island in Canada to Cape Mendocino in Northern California, the CSZ is a dipping fault line that has been the source of some of the most powerful earthquakes ever recorded. These quakes can result in underwater (also known as submarine) landslides, which can lead to tsunamis.
