Time reverse imaging for far-field tsunami forecasting: 2011 Tohoku earthquake case study

Hossen, Jakir; Cummins, Phil; Dettmer, Jan; Baba, Toshitaka

Description

This paper describes a new method for forecasting far-field tsunamis by combining aspects of least squares tsunami source inversion (LSQ) with time reverse imaging (TRI). This method has the same source representation as LSQ but uses TRI to estimate initial sea surface displacement. We apply this method to the 2011 Japan tsunami, and the results show that the method produces tsunami waveforms of excellent agreement with observed waveforms at both near- and far-field stations not used in the...[Show more]
