Submarine landslides and earthquakes can generate, FTP, these large, potentially devastating waves.
A 12-point scale proposed by Papadapoulos and Imamura has replaced the Sieberg-Ambraseys intensity scale for these events. They generally propagate as long-wavelength gravity waves at a speed given by the square root of the gravitational acceleration times the depth. They can generate seiches and trapped modes known as edge waves that travel along the coastline. They convert kinetic energy to potential energy while shoaling, producing runup out to the inundation line.
