Upgrade of the Dynamic Simulation Procedure for Near-Field Tsunamis

Abstract

The 3-D dynamic tsunami simulation procedure developed by the authors takes into account the dynamic seabed displacement resulting from seismic faulting and acoustic effects of seawater. Some new techniques have been developed for upgrade of the existing procedure, which include the so-called nesting of the mesh size and extension for run-up to coastal areas. Practicality of the upgraded procedure has been successfully validated by, for example, simulation of the dynamic generation of a near-field tsunami followed by the propagation and run-up.
