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.
We study techniques for the real-time ground motion prediction and the earthquake damage estimation using the land and sea integrated seismic data toward mitigation of earthquake disasters.
