Tsunami Prediction for the Specific Site Considering Uncertainty of Fault Parameters

It may be possible to inform the tsunami warning such as tsunami wave height and arrival time just after an earthquake occurs, if we simulate many cases of the tsunami propagation in advance. However, it is not clear how the fault parameters influence on the tsunami of a specific site. This study calculated about 1200 tsunami propagation cases for the Akita Oil Storage Base to survey the influence of the uncertainty of the fault parameters. The tsunami wave height was related to the initial vertical displacement of the sea bottom although the location of epicenter varied the height. The arrival time was related to the distance from the epicenter and the magnitude of earthquakes.
