What is the Meaning & Definition of tsunami
Hyper-violent agitation that occurs in the riverbed underwater and caused by an earthquake
One of the most significant natural disasters that exist by the physical injury and property damage who knows cause in its path is the tsunami and consisting of a hyper agitation violent that occurs in marine waters and that it is caused by an earthquake in the underwater bed. Its consequences on the coast are certainly devastating, because it is precisely in this place where all the damage is concentrated.Devastation on the coast. The dramatic case of Indonesia in 2004
As we noted the tsunami is extremely violent agitation of the submarine waters sea phenomenon is able to extend to the coast and cause stunning floods, which unfortunately we could contemplate very recently ago, more precisely of December 26, 2004, in the Asian continent and had its epicenter on the West coast of Sumatra Indonesia, when there was an earthquake erupted in the Indian Ocean, which caused the endless flood of much of coastal populations, such as Indonesia and Thailand.So to give you an idea of the scope and seriousness that this type of natural phenomenon presents enough just to remember that happened made wretched figures five years ago: 230 thousand people, Bob recorded a 9.3 on the Richter scale, made that made him almost a record, being the second largest earthquake since the seismograph was invented.
Earthquake in the bottom of the sea with vertical scroll
This alteration mentioned so often occurs at the bottom of the sea and is usually due to an earthquake that occurs there himself and which generates the vertical displacement of the water. This type, formally, it is called it as a tectonic tsunami.The Pacific Ocean, the more prone because of their characteristics
Any of the oceans of our planet can accommodate a tidal wave, though, the Pacific Ocean, is prepared is by their physical characteristics in the margins, particularly on the coasts of Chile, Japan and Peru.In these places, as a result of the familiarity with the phenomenon, there are protocols of emergency that the population living in coastal areas should follow in the event that you feel a tremor of consideration, which of course, can follow a tidal wave.
Large waves and that they take all their virulence coasts
Other causes may be landslides, eruptions of volcanoes, explosions at the bottom of the sea. The violent movement of the water from the deepest is capable of generating an effect that rises up to the surface, generating large waves and that convey all its virulence to the coasts.Major erosion damage to the surface of the beach
The turbulence that knows to generate in its wake tsunami dragging rocks and sand that convey important erosion damage to the surface of the beach and that changed the geography of the place for a very long time.New technologies that allow to anticipate and other notices
New technologies as the satellites allow to anticipate the presence of significant changes in the waves, with times measured the height, the volume and the speed of the wave. Now, there are other signs that allow us to anticipate a tsunami, such is the case of an earthquake of long duration and high intensity; the abnormal reverse of the sea; and prolonged shaking of the Earth. All of this can be the prelude to a tidal wave.In addition, the concept of tsunami is used without much discrimination for the common people when you want to refer to the giant waves that occur when instances of hurricanes or strong storms of wind and rain.
