[HDS11-01] Observation-based research toward mitigation of earthquake-induced landslides –expansion of slope seismology -
Studies were performed for earthquake-induced landslides from geological, geographical, geotechnical and numerical simulation approaches. Evaluation for the risks and countermeasures were mainly based on peak ground acceleration (PGA). On the other hand, observations of the ground motion and ground water pressure in the slope during earthquake are insufficient, which result in the fact that we do not fully understand the detailed mechanisms of earthquake-induced landslides. In this presentation, we introduce the results of our observation in the slopes of various types and discuss what is necessary to understand the generation mechanism of earthquake-induced landslide.
