Marine Geology 239: 99¿123 doi:10.1016/j.margeo.20 Goff, J. When an earthquake occurs, this system automatically computes preliminary information on the earthquake's origin time (time at which the earthquake happened), location, depth and magnitude.Most tsunami are caused by large earthquakes on the sea floor when slabs of rock move past each other suddenly, causing the overlying water to move.The resulting waves move away from the source of the earthquake event.Higher oceanic wave heights are sometimes observed very close to the tsunami generation zone (e.g., oceanic waves near two metres were measured close to the source of the 2011 Japan tsunami).In any case, the shoaling effect can greatly increase open ocean wave heights upon reaching the coast, with some tsunami reaching an onshore height more than ten metres above sea level.Tsunami (pron: 'soo-nar-me') is a Japanese word: 'tsu' meaning harbour and 'nami' meaning wave.

Tsunami are waves caused by sudden movement of the ocean surface due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean.Such extreme inundation is more likely to occur nearer to the tsunami generation location (where oceanic wave heights are larger), and at locations where the coastline shape is particularly favourable to amplification of the tsunami.Most tsunami do not cause such extreme coastal inundation and the effect of small events may not be noticeable to without careful analysis of tide gauge measurements.Several significant tsunami have impacted Australia's north west coast region.The largest run-up (measured as elevation about sea level) was recorded as 7.9m (Australian Height Datum (AHD)) at Steep Point in Western Australia from the July 2006 Java tsunami.
