computer model prediction model validation became possible.
Calculation methods such as TSUNAMI-N2 of United States
Oceanic and Atmospheric Administration of the product model
and Tohoku University has been developed. Tsunami
simulation technology is utilized to tsunami forecasts and
hazard map making. Also can cause a 2.5 m world's largest
