".An earthquake generated in a subduction zone will head in both directions, mainly at right angles to the fault line that created it. "After a big underwater event in deep water, say about 5 kilometres, the wave is probably moving at around 800 kilometres an hour, [or] about the speed of a jet," Professor Goff said. A dangerous tsunami is a series of waves that can be triggered by any event that disrupts the sea floor in some way.They are usually caused by underwater earthquakes, but can also be caused by underwater landslides, nuclear weapons testing and even asteroids falling into the sea.So why do tsunamis occur, and how does the monitoring system work?Tsunamis can occur when there is a sudden movement or change within the ocean.The majority are caused by underwater earthquakes, but there are a number of other events capable of triggering large waves, according to James Goff, Professor of Tsunami Science at the University of New South Wales.An underwater volcanic eruption is one such event. But the sense of displacement is also important.
