The Geoisostasy and the Physical Nature of Tsunami:Conditions of Originating and Possible Paths of the Prognosis

Using geoisostasy phenomena,the author has got the answers for some questions about tsunami physical nature.Equilibrium state conception of the rotated Earth as the planet(geoisostasy)was shown on theⅩⅩⅧsession of the International Geological Congress for the first time.According to geoisostasy conception there are some conditions that must fulfill tsunami development:(1)ocean-floor tectonic motions must have significant vertical components;(2) vertical displacements of tectonic blocks must
