Outline of Research Topics
The research is focused on earthquake sources, seismic wave propagation, and site effects to study ground motion characteristics and to develop advanced methodologies of strong motion prediction for evaluating the seismic hazard from destructive earthquakes.
1. Seismic Wave Generation in Earthquake Source
- Source modeling using strong motion data (kinematic waveform inversion, EGF method, etc.)
- Characterization of heterogeneous fault rupture process for inland crustal, subduction, and intraslab earthquakes
- Near-source and extreme ground motions controlled by the source process
Source models of recent inland earthquakes in Japan obtained from strong motion data
2. Seismic Wave Propagation and Site Effects
- Analysis and modeling of long-period ground motion generation and propagation in crust and basin structures
- Investigation of site effects considering effects of surface geology
- Subsurface exploration using seismological techniques
- Seismic array observation in Kyoto
Microtremor observation at a strong motion station
3. Strong Motion Prediction for Scenario Earthquakes
- Development of theoretical and semi-empirical broadband strong motion simulation methods
- Development of strong motion prediction recipes for scenario earthquakes
Long-period ground motion prediction in osaka basin from the anticipated Nankai earthquake
Strong Motion Obaservations
- Three-dimensional Array Observation in the Uji Campus of Kyoto University
- Strong motion observation at the Clock Tower Centennial Hall of Kyoto University
- Strong motion array observation in Kyoto basin
