Development of Algorithms for Earthquake Early Warning and Their Practical Applications

Earthquake Early Warning System has attracted research attention recently as a method to mitigate seismic hazard. It is a system to estimate earthquake properties in real-time and take an action before the strong shaking arrives at a site.

Landslide Seismology

Recently, seismometers are used to monitor various natural disastors. In this study, we use sesmic signal to study landslides. We try to achieve landslide forecast, real-time monitoring, and understanding of mechanisms.
