Their movement is similar to that of sound, as both are compressional waves. They can be caused by landslides, such as a small one which hit Nice, France in 1979, or volcanoes, such as an 1883 one in Java, but more often they are caused by a combination of these events. They are mainly caused by earthquakes which tilt the sea bottom and set off on large scale the same ripples that come from throwing a rock in a pond. FTP,
