Abstract: | This study employs an empirical-analytical approach in combination with Monte-Carlo method to establish relationships between
earthquake moment magnitude and upper limits of tsunami source parameters: double-amplitude of vertical bottom deformation,
displaced water volume, and potential energy of initial elevation. The approach is based on the Okada solution for a finite
rectangular fault and empirical scaling laws for earthquake sources. Results are compared to empirical and theoretical relationships
published previously. Parameters of some recent tsunami sources, those for which USGS provides slip distribution data, are
considered in light of the established relationships. |
