Such a wave travels at well over 800 kilometres per hour (500 mph), but due to the enormous wavelength the wave oscillation at any given point takes 20 or 30 minutes to complete a cycle and has an amplitude of only about 1 metre (3.3 ft). The earthquake was said to had magnitude 9.3 on the Richter scale. Since the wave still has such a long wavelength, the tsunami may take minutes to reach full height. It is also for this reason that there would not be any drawback when the tsunami travelling on the other side arrives ashore, as the tectonic plate is "raised" on that side of the fault line.Drawback begins before the wave's arrival at an interval equal to half of the wave's period. During the Indian Ocean tsunami, the sea withdrew and many people went onto the exposed sea bed to investigate. Difficulties in calculating the potential energy of the tsunami means that this scale is rarely used.The following have at various times been associated with a tsunami:Tsunami are not rare, with at least 25 tsunami occurring in the last century.
The first wave to reach the shore may not have the highest run up.About 80% of tsunamis occur in the Pacific Ocean, but are possible wherever there are large bodies of water, including lakes. People who do not know of the danger will often remain at the shore. The giant wave moved very quickly. Over 215,000 people died from this disaster. Professor Costas Synolakis of the Tsunami Research Center at the University of Southern California co-authored a paper in Geophysical Journal International which suggests that a future tsunami in the Indian Ocean basin could affect locations such as Madagascar, Singapore, Somalia, Western Australia, and many others. Its wavelength diminishes to less than 20 kilometres (12 mi) and its amplitude grows enormously, producing a distinctly visible wave. Run up is measured in metres above a reference sea level.
Ships rarely notice their passage.As the tsunami approaches the coast and the waters become shallow, wave shoaling compresses the wave and its velocity slows below 80 kilometres per hour (50 mph). It was centered in the ocean near the coast of Sumatra, Indonesia. Few survived.The first scale that genuinely calculated a magnitude for a tsunami, rather than an intensity at a particular location was the ML scale proposed by Murty & Loomis based on the potential energy. (For the plural, one can either follow ordinary English practice and add an s, or use an invariable plural as in the Japanese. Of these, many were recorded in the AsiaâPacific regionâparticularly Japan.The 2004 Indian Ocean tsunami killed over 200,000 people with many bodies either being lost to the sea or unidentified.According to an article in Geographical magazine (April 2008), the Indian Ocean tsunami of December 26, 2004 was not the worst that the region could expect. They may be caused by landslides, volcanic explosions, bolides and seismic activity.If the first part of a tsunami to reach land is a trough (called a drawback) rather than a wave crest, the water along the shoreline recedes dramatically, exposing normally submerged areas.A drawback occurs because the tectonic plate on one side of the fault line sinks suddenly during the earthquake, causing the overlaying water to propagate outwards with the trough of the wave at its front. It was caused by an earthquake.
