Strong motions of JMA seismic intensity of 7 were observed near the surface rupture at Mashiki town and Nishihara village during the 2016 Kumamoto, Japan, mainshock. We carefully integrated the observed acceleration records to velocities and displacements with correcting the base-line change in acceleration records, which would be caused by the effect of tilting of the seismometer. The corrected observations show large permanent displacements, which include near-fault terms. The amounts of permanent displacements coincide to geodetic observation results. We discuss those ground motion characteristics and compare those with other near-fault ground motion records.
