Phenomenon of Tsunami

A tsunami is a series of waves caused by earthquakes or undersea volcanic eruption. Due to sudden changes in seafloor caused by earthquakes, submarine landslides, volcanic eruptions. The waves travel higher and higher heights as the depth of the ocean decrease as the waves travel inland. Out in the depths of the ocean, tsunami waves do not dramatically increase in height. The source of the wave of the tsunami speed depends on the ocean depth rather than the distance from the source of the wave.

Tsunami waves may travel as fast over deep waters, only slowing down when reaching shallow waters. These waves are typically caused by large, undersea earthquakes at tectonic plate boundaries. When the ocean floor at a plate boundary rises or falls suddenly, it displaces the water above it and launches the rolling waves that will become a tsunami. An active area where tectonic shifts make volcanoes and earthquakes common.

They are caused by earthquakes that occur on the seafloor areas. Transmitted through the water-energy generated by the earthquake. Tsunamis travel across the open ocean at great speeds and convert into large deadly waves in the shallow water of a shoreline. In these sea waves can travel unnoticed because the wave height may be small. When the shallow water of the coastlines it forces into a giant wave with the energy wave. Tsunamis where an oceanic plate is forced down in the mantle by tectonic plates forced are caused by earthquake generated in a zone. The friction between the subducting plate is huge. The rate of subduction a slow and steady rate the two plates become stuck. A tsunami is a series of waves that can move onshore rapidly but last for several hours and flood coastal communities with little warning. They have taken many lives in Hawaii, Alaska, Puerto Rico, the Virgin Islands, California, Oregon, and Samoa. "More recently, tsunamis generated by earthquakes in West Java (July 2006), Samoa (September 2009), and Chile (February 2010) have flooded some U.S. coastlines, highlighting the need for a focused and well-coordinated effort to minimize the loss of life and property" ( National Academies Press, 3). tsunami waves can travel at speeds up to about 805 km per hour. Tsunamis have a height ranging from 30-100 feet tall and can raise an extra 20 feet when it enters shallow water ( National Academies Press, 5).

The height of the wave can increase and become very powerful winds. The wave will look normal but as soon as it gets closer it looks much bigger. As soon as it hits the coast it still will travel at the same speed for a couple of meters. The area will be flooded and will likely be covered in objects swept on the shore from the sea. When a tsunami moves back and forth in the water it will end up becoming a vertical in the water. These waves can continue many days after a tsunami has occurred. It's impossible to stop a tsunami but you can help control the damage that will occur. One of those ways is by building walls. The National Academic Press believes that the wall would be built out of something that is strong enough to hold the wall up during a tsunami-like steal. The problem with that s that would limit the area to swim. A common one would be an alarm that could go off every time there is a tsunami warning, if something like this was put up at every coastal city, it would reduce the number of deaths from tsunamis. This would have helped a lot in the Indian Ocean tsunami.

Communities in the distance from the triggering event might feel the ground shaking only weakly and not recognize the need to evacuate although a tsunami could arrive in as little as an hour. Two separate U.S. TWCs monitor seismic activity and sea levels in order to detect tsunamis and warn of their presence (National Academies Press, 109). The emergency managers in their respective and complementary areas of responsibility decided whether to issue alerts based on data. They should provide timely warnings of the tsunamis but also must obviate needless evacuations that can cost money and even lives. Emergency managers with the necessary information to call for an ideal warming evacuation in a timely fashion at any particular location. The general public easily understands the ideal product of the threat and who is affected by the threat of the tsunami ideal path. The duration of the damaging waves includes predictions of the time of arrival of the ocean waves. Therefore, the warning system needs to be prepared to respond to a range of scenarios. The tsunami can arrive minutes after an earthquake to a tsunami that arrives many hours after a triggering last for many more hours due to the waves' scattering. In the case of the near-field tsunami, major challenges remain to provide warnings on such short timescales. If you hear a tsunami warning in your home, make sure your family knows about it. When living near the coast you should always be ready for a tsunami at any second. Tsunamis move much faster than anyone can run, so there is no point trying to outrun it, you must evacuate beforehand. When there is a tsunami warming and if you are at sea get away and don't go near shore anymore. When evacuating, always have a survival kit.

You will know it is completely so until you should stay in a safe place. A computer can provide a time of arrival in minutes. they can erosion potential, beaches of sand with its energy through the destruction. The generating source area waves travel outward in a direction like throwing a rock into a pond. Tsunami is natural events that threaten coastal communities. In the wake of the catastrophic 2004 Indian Ocean tsunami, widespread destruction, is natural events that threaten coastal communities. The Indian Ocean tsunami hit the coast of several places of South and Southeast Asia in December. This tsunami had a series of immense ocean waves across the ocean. The tsunami killed at least 225,000 people across a dozen countries, with Indonesia, Sri Lanka, India, Maldives, and Thailand sustaining massive damage (Mercado, 152). In the Indian territory, a large amount was reported missing. In some of the low lying islands, there was a number of reports of economic damage. With this issue of the tsunami, there was a lack of essential that we need to excel in life like food, clean water, and treatment. Also, trying to fix some remote areas where roads had been destroyed. Since, the islands were damaged as well as villages, resorts, villages, etc they are covered in debris, salt water, and bodies. There, waves reached 80 feet high over large stretches of the coast and up to 100 feet in some places (Gilbreath, 143). Swept away by water in a matter of minutes were entire communities. The death toll in Indonesia is estimated at between 130,000 and 160,000 people, with an additional 500,000 people left homeless. About a third of the victims were children (Gilbreath, 145).

It was the worst tsunami in recorded history. There were no alert services around the Indian Ocean to help people in time of the tsunami. When the tsunami disaster occurs everyone, not just the one area the whole felt the devastation. The world comes together and supports to help clean up the mess of the tsunami. Instead of the different parts of the world should deal problems countries can come together and help fix the devastation. The impact of tsunami debris flowing through landslides shows a major crisis of a natural event. The ultimate natural disasters are tsunami disasters which will lead to the loss of several lives and properties. To recover from theses terrible disaster many groups and companies, and schools donated money to organizations like the Red Cross.
