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.

Academic Significance and Societal Importance of the Research Achievements

津波の予測において、その予測が過大あるいは過小である可能性は常に存在する。したがって予測情報の活用にあたっては、その推定値の「正確度」と「精度」を適切に把握することが重要である。本研究ではこれらを推定可能な手法を提案するとともに、現実的な地形条件・観測条件・想定津波波源を用いた検証によりその有効性を確認しており、学術的に重要である。さらに遠地津波予測においても、高い精度の波形予測計算を実用的な時間で演算可能なプログラムを開発した。これらは実際の予報業務への適用も期待される重要な成果である。
