The tsunami of Japan was the result of two waves

The tsunami generated by the earthquake of Tohoku-Oki, during the march of 2011, which destroyed the north coast of Japan, was as a result of the fusion of two giant waves which increased the intensity of the tsunami. Two scientists analysed the information taken by three satellites (in Europe and in the USA) and they confirmed the same conclusion. Theirs hypothesis was that two waves were added to the principal tsunami. This phenomena had a very difficult precision of the projections of this giant waves.

Y.Tony Song (Jet Propulsion Laboratory, California) and C.K.Shum (The Ohio State University) base their investigation on the information obtained by the Radar Altimetry “Jason I”, “Jason II” and “Envisat” satellites, that measure the highest of the sea by a pressure of a few centimetres. They overestimate the region of the earthquake and the tsunami, followed by lightly different trajectories and separated by a little hours, but they measure the different points of great waves. The facts, indicate that two of those points of great waves, were formed the same day that the earthquake was generated. Those two points were fused to form an only tsunami, which was double higher. This tsunami took long distances without losing its power.

The results of the investigation, help to explain how the tsunamis can go through the ocean an provoke grave damages in specific zones without suffering in other zones. In addition, this investigation can help to improve the prediction of the tsunamis and the emergency systems to avoid them.
