Development of real-time prediction method of tsunami water level in coastal zone, using tsunami propagation effect

In order to rapidly predict tsunami water levels in coastal zones where the water depth is deeper than 50 m, a method is proposed which convolutes tsunami water levels observed in the sea and tsunami propagation effects excited by a small fault. To predict tsunami water levels in coastal zones where the water depth is shallower than 50 m, a method is proposed which uses a small-scale tsunami numerical simulation. This study investigates the validity of the proposed methods, by applying these methods to numerical simulation data for the 2011 off the Pacific coast of Tohoku earthquake (Mw 9.0).
