| Outline of Final Research Achievements |
It is difficult to predict the occurrence of tsunamis in advance, but there is a possibility to make a prediction based on offshore tsunami observation even before tsunami attack on land. Regarding such real-time forecasting, we have developed a method for quantitative estimation of the accuracy and the precision simultaneously. This method was evaluated through the application to the Tokyo Bay in cases of three scenario tsunamis. The estimation results show good agreements with the given scenarios. Furthermore, parallelization of tsunami propagation simulation program was implemented to enable highly accurate prediction of tsunami waveforms in areas far from the tsunami source. The implementation made it possible to conduct the far-field tsunami simulation with high accuracy in a practical computation time.
