Department of Seismology and Tsunami Research
The aim of our research is to elucidate the mechanisms of earthquake and tsunami generation and propagation. We also seek to further develop prediction methods for ground motion and tsunamis, improve technologies for monitoring crustal activity to forecast seismic activity, and develop and refine instruments and data processing technologies for earthquake and tsunami observations. The outcomes of these studies contribute to improving disaster prevention information on earthquakes and tsunamis issued by the Japan Meteorological Agency.
Ordinary Research: Research on Monitoring and Forecasting Crustal Activity, Seismic Ground Motion, and Tsunamis
Our aim is to deepen our understanding of crustal activity, seismic ground motion, and tsunami-related phenomena, and to develop and improve monitoring and forecasting technologies for earthquakes and tsunamis, in order to prevent and mitigate disasters associated with such events.
Objectives
- Enhance data processing technologies for the immediate characterization of earthquakes, including applying new technologies to seismic observations, automated processing, and the rapid identification of fault rupture areas following an event.
- Improve the accuracy of understanding changes in interplate coupling conditions and the development of earthquake occurrence scenarios. Clarify the relationships between crustal deformation fields and seismic activity.
- Improve the accuracy, immediacy, and robustness of real-time ground motion prediction using wavefield-based algorithms, and extend the algorithms for long-period ground motions.
- Effectively improve tsunami early warning and forecasting methodologies for regions near the tsunami source, intermediate distances, and far-field regions.
