Outline of Final Research Achievements

As for the prediction of tsunami scale, which is significant in tsunami disaster prevention, it has been difficult and never been established to give a value of magnitude of a tsunami, like that of an earthquake as an energy index of the earthquake scale, in quasi-real-time only by remote-sensing observation on land.
In this study, we established an infrasound (inaudible low-frequency sound, or microbaric waves) observation network in Kochi Prefecture, as a model region. Based on characteristic period and maximum amplitude of the observed infrasonic waveform data, obtaining characteristic length and height of the area of sea-surface rise immediately after an event of earthquake, variation of the potential energy at the event of a tsunami can be obtained, that is, the information corresponding to energy changes is remotely monitored by a group of sensors distributed on land. It has been shown that the Infrasound Tsunami Magnitude can be calculated by the infrasound observation network.

Academic Significance and Societal Importance of the Research Achievements

津波に対する規模の指標として「津波マグニチュード」を与えることは、従来の手法では地震に対するマグニチュード推定のようには実現できず、事後の津波遡上高の分布を広大な領域で調査し総合的に判断する必要があり、準リアルタイムでこれを与えることは極めて困難であった。本研究手法では、陸上設置のインフラサウンド(超低周波音、微気圧波)観測網による観測波形から「インフラサウンド津波マグニチュード」を準リアルタイムで算出できることが示された。これは津波防災への情報提供手段として画期的であり、防災ならびに安全安心な社会の実現に対する貢献可能性を示す学術的・社会的に大きな意義のある研究成果である。
