| Outline of Final Research Achievements |
Seismic design does not consider multiple motions. So it may underestimate earthquake damage against continuous earthquake. In the 2016 Kumamoto earthquake, 2 intense earthquakes of 7 on the Japanese seismic intensity occurred for a short span of time. So, the 2016 Kumamoto earthquake is regarded as a continuous type earthquake. We attempt damage assessment of the houses by using the aerial photographs after the earthquake. And we compare the house damage before and after the earthquake and estimate progress of the house damage. Furthermore, we make a source model of 2016 Kumamoto earthquake as a continuous earthquake by forward modeling using the empirical Green’s function method. And we make a source model of 2016 Mid. Tottori earthquake of Mj6.6 and 2017 South Nagano earthquake of Mj5.6 for upgrade of the source modeling of the crustal earthquake.
