Earthquake and Tsunami Research Division

In the Earthquake and Tsunami Research Division, analyses of observation data from the foundational earthquake and tsunami observation network, and various studies on numerical simulations and laboratory experiments have been conducted. Through these studies, fundamental research on earthquake and tsunami have been done. In addition, development of new realtime prediction technologies for earthquake and tsunami and long-term forecasting methods for large earthquakes are conducted aiming at the mitigation of earthquake and tsunami disasters.

   - Real-time seismic motion prediction and earthquake damage estimation technologies.
   - Research on tsunami prediction technology.
   - Research on sophisticated long-term evaluation of earthquake occurrence.
   - Research on large earthquake generation mechanism.
