Landslides can happen on the seafloor, just like on land. The waves travel at a great speed across an ocean with little energy loss.

Tsunami Mitigation and Prevention . It is made up of two equally important components: a network of sensors to detect tsunamis and a communications infrastructure to issue timely alarms to permit evacuation of the coastal areas. Waves will take some time to reach the coasts. Tsunamis, like most natural disasters, are beyond human control. The tsunami that struck Banda Aceh, Indonesia, on December 26, 2004, washed a 2,600-ton ship about five miles (eight kilometers) inland into the city. In general, tsunamis are not particularly threatening, as they constantly happen every day around the world, often in the middle of the ocean. A tsunami warning system (TWS) is used to detect tsunamis in advance and issue the warnings to prevent loss of life and damage to property. Another effective method from a tsunami is proper planting trees. Usually, a tsunami starts suddenly. The resulting waves move away from the source of the earthquake event. Tsunami protection engineering is intended to prevent or mitigate possible tsunami damage and save lives. In fact, most tsunamis don't reach much higher than regular ocean waves on the beach. A tsunami is a series of waves created when a body of water, such as an ocean, is rapidly displaced. Tidal Wave (Korean: 해운대; RR: Haeundae) is a 2009 South Korean disaster film directed by Yoon Je-kyoon and starring Sol Kyung-gu, Ha Ji-won, Park Joong-hoon and Uhm Jung-hwa.Billed as South Korea's first disaster film, the film released theatrically on 22 July 2009 and received more than 11 million admissions nationwide. Tsunami prevention 25 January 2017 Devastating tsunamis could be halted before hitting the Earth’s shoreline by firing deep-ocean sound waves at the oncoming mass of water, new research has proposed. Tsunamis are infrequent but very dangerous natural hazards that threaten the coasts and inland waters of California, Oregon, Washington, Alaska, Hawaii, and territories in the Pacific region, as well as Puerto Rico and the Virgin Islands in the Caribbean. Tsunami occurs usually after major earthquakes or large landslides within the ocean. But in some cases, the tsunami will develop into potentially destructive waves. There are, however, a number of techniques that can minimize the harmful effects of tsunamis to the physical environment (including built structures) and to individuals and communities. The 2004 Indian Ocean earthquake and tsunami (also known as the Boxing Day Tsunami and, by the scientific community, the Sumatra–Andaman earthquake) occurred at 07:58:53 in local time on 26 December, with an epicentre off the west coast of northern Sumatra, Indonesia.It was an undersea megathrust earthquake that registered a magnitude of 9.1–9.3 M w, reaching a Mercalli intensity up to … The best method of protection seems to be the use of seawalls in front of ports and cities. 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. A tsunami is a natural disaster which is a series of fast-moving waves in the ocean caused by powerful earthquakes, volcanic eruptions, landslides, or simply an asteroid or a meteor crash inside the ocean.A tsunami has a very long wavelength.It can be hundreds of kilometers long.
