Time reversal imaging of the tsunami source

Hossen, Jakir; Cummins, Phil R.; Roberts, Stephen G.; Allgeyer, Sebastien

Description

In this paper, we apply time reversal imaging (TRI) to the problem of reconstructing the initial sea surface displacement that generates a tsunami. We discuss theoretical considerations in the application of TRI to the tsunami problem, including time reversibility and reciprocity of the shallow-water equations. Several numerical experiments are conducted to establish the efficacy of TRI in the tsunami context. TRI is applied to observations of the tsunami generated by the Tohoku earthquake on...[Show more]
