Abstract

An analytical model of tsunami generation by an earthquake has been built by taking into consideration some parameters of the source and the properties of the Earth’s crust. This model allows to get a solution of the problem in a simple form whose study is performed only through analytical means. The following phenomena are discussed: the tsunami height is studied in a 2D space as a function of the seismic focus depth for vertical-fault point- and line-sources and the maximum of this function is examined; the concept of “continuation” of a tsunami in the Earth’s crust is illustrated; the dependence of the tsunami height and energy on the rise time and on the duration time of the dislocation at the source is faced. Eventually some considerarions are made on the “tsunami earthquakes” and on the differences between the Mediterranean and the Pacific Ocean tsunamis.
