| Outline of Final Research Achievements |
Fault displacement and strong ground motion in Shikano town, Tottori city under the 1943 Torrori earthquake are examined as typical damage of strike slip earthquake. Disaster situation in the town is reconstructed from several photos by the survey team at that moment. Seismic intensity distribution were also investigated from questionary survey. Fault slip model of the earthquake is developed using the information above considering survey results of the 2016 Kumamoto earthquake. Strong ground motions including permanent displacements are simulated adding effects of surface geology estimated in the target area. Seismic response of old wooden house which survived from the 1943 Tottori earthquake, is evaluated. The house also survived from simulated wave at the location, but collapsed by an estimated wave at heavily damaged area. It is also found that typical predominant periods are not clearly distinguished in the vicinity of surface faults. It can be a further research subject.
