Abstract
The coseismic crustal deformations due to the 2016 Kumamoto Earthquake are numerically obtained using GEONET data. We further estimate coseismic strains of ground from the deformation data. The seismic intensity due to the earthquake is also obtained with use of strong motions by K-NET, KiK-net and other observation systems. Both parameters of the coseismic strains of ground and seismic intensity are compared with damage data of civil engineering structures. This paper especially places emphasis on comparisons between the coseismic strains and damages to soil structures such as ground slope. It is concluded that coseismic strains of ground mainly caused damages to ground slope and the characteristic distribution of coseismic strains in space resulted from the source mechanism of the 2016 Kumamoto Earthquake that had a strike-slip fault plane (right-lateral) with the break spread to the northeast direction.
