Outline of Final Research Achievements

To monitor and understand the mechanism of landslides using seismic waveforms, we analyzed the dynamic history of landslides, developed a method for efficient landslide detection, developed a landslide tsunami simulation and warning system using seismic waveforms, clarified the frictional characteristics of landslides, and analyzed repeated earthquakes. Detailed analysis of multiple events revealed that seismic records have the potential to provide information such as rapid detection of landslides and tsunami warnings and prevent the secondary disasters.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は、現在まだ達成されていない地すべり即時検知システムを構築するための学術的基礎資料となるものである。地すべり運動と地震波形の関係を詳細に解析することにより、地震波形から地すべり運動を逆問題として推定することが可能となる。この研究成果が実用化されれば、将来は、地すべりの発生位置・時刻を遠隔かつリアルタイムに検出することが可能となる。また、地すべりが海底あるいは海岸で発生した時には、津波警報を出すことができる。
