Yet, by studying a 43 million - year record of submarine landslide deposits from sediment cores, this research reveals that submarine volcanism can generate landslides many times larger than those recorded above the sea. (sciencedaily.com)
The drill cores not only contain landslide deposits, known as turbidites, but also a continuous record of the background sediment that can be used to accurately date the turbidites. (sciencedaily.com)
It used measurements from 195 core samples containing submarine landslide deposits caused by subduction zone earthquakes, instead of only about a dozen such samples in past research. (sciencedaily.com)
