Research Subject(s)
We are working to improve methods for predicting strong ground motion, focusing primarily on areas near faults. The study focuses on methods for establishing fault models with a primary emphasis on the application of geological and topographical data, as well as on the consideration of uncertainty and diversity.

Research Activities

The setting of the source-fault model is important as it directly influences the simulation of strong ground motion and tsunamis, and consequently affects the predicted damage, as well as the associated disaster prevention policies and measures. In practice, this provides fundamental information on the earthquakes that should be assumed, and it is essential to reduce underestimation and improve the clarity of the information provided. We are conducting studies to propose methods for processing simulation results that encompass multiple possibilities and a range of variations by incorporating uncertainty and variability into the configuration of the source fault model. We aim to contribute to future disaster prevention efforts by reducing the underestimation of assumed earthquake risks.
