HYDRAULICS OF TSUNAMI
Abstract
This study given a simple physic and hydraulics explication behind earthquake, called Tsunami. This explication based to energy conservation equation and wave properties have bind used to understand this phenomenon. As we calculated, the Energy E, Velocity v and wave length $\lambda$ of tsunami are decreased but the amplitude of tsunami wave A is increased when it reaches the land, respectively. The changing of wave height when it close to the shore makes tsunami difficult to be detected at early stage. From our first calculation of radiation earthquake energy using Gutenberg-Richer formula the huge В« explosion В» energy undersea at 00 :58 :50 (UTC) or 160 km from North Sumatra as the Tsunami by 26 December 2004, is approximated to 1 gigatons of TNT equivalent to 80000 В« Little Boy В» Hiroshima atomic bomb, where it is initial area for Tsunami wave to propagate.
