ИСТИНА

Tsunami intensity, according to the Soloviev-Imamura scale, is a reasonable and well-adopted measure of tsunami size. This parameter can be taken from the Historical Tsunami Database for the World Ocean. In this study, we consider some recent tsunami sources, those for which USGS provides slip distribution data (Finite Fault Model). From the Finite Fault Model, applying the Okada formulae, we calculate realistic co-seismic bottom deformations which allow us to determine the following set of tsunami source parameters: double-amplitude of bottom deformation, displaced water volume, and potential energy of initial elevation. Ultimately, we obtain and discuss dependences that relate the tsunami intensity and the parameters of tsunami source.
