Tsunamis are a frequent seismic waves caused by earthquakes as the tectonic plates beneath the ocean floor collide. This
is sometimes not an earthquake tsunami itself, but may be in order to
run it, as a result of sea landslides caused by the initial earthquake. This
led to mass erosion surface of the water in the lines that often get
better as a result of training in large waves in shallow coastal line of
bad hike. The third cause tsunamis is volcanic eruption. Earthquakes marine
Oceanic earthquakes far the most common cause of tsunamis. The reason is that the tectonic plates beneath the surface. They are located under the seabed sometimes rub or collide with each other, which causes a lot of energy to expel. It's heat and energy caused by water as a result of the pressure exerted from the bottom up. To make it clearer what actually happens during an earthquake in the sea is that the heavy tectonic plate trying to make its way through the push. Tectonic plates under the lighter plate is always to condensed matter such as stones, which runs along the asthenosphere version, partially skinned weaker than the Earth's mantle. Plate tectonics also called litospheric plates moving together is known about the asthenosphere.Tsunami occurs because, while the heavy plate trying to slide under the lighter, may end up stuck pushing pressure that leads between the two plates as the weight of the construction. Mild lateral plate and down What happens then is that the light reaches its limit plate is pulled down, suddenly snaps back to the original surface, which causes the pressure exploded upward. This pressure forced the water up, which forms a humongous shaft.
The Ring of Fire
Tsunamis can be so powerful that they can travel thousands of miles just beyond the banks to crash. Most tsunamis occur in the Pacific Ocean is the largest body of water on Earth. It covers rd 1/3 of the earth's surface and is surrounded by deep ocean trenches, island arcs and mountain landscape. Therefore, this area is often called the "Ring of Fire" because it is vulnerable to earthquakes.With about 2/3 rd of the sea world, the consequences of strong earthquakes oceans have been a disaster. An example of the impact of the tsunami, the Christmas tsunami that struck the Indian Ocean in 2004. The fact is that the earthquake occurred on the island of Sumatra, and the magnitude of the earthquake was 9.2 on the Richter scale. The earthquake caused a series of tsunamis that swept across Indonesia, India, Madagascar and Ethiopia! This tsunami was the worst, she claimed the lives of more than 283,000, and completely destroyed the landscape, buildings and all things related.Hopefully, now you know more about tsunamis and why they took place. Other possibilities, such as a tsunami can be created Due meteoric impact and artificial phenomena such as nuclear weapons test underwater in the sea. Scientists have not come up with a way to prevent a tsunami if certain steps are taken to allow us, as if approaching tsunami through the identification of a specific set of satellite fields and read waves predict.
