The spatial distribution of the coseismic displacements
that occurred along the Futagawa fault during the 2016 Kumamoto earthquake
of Mw 7.0 was estimated using airborne light detection and ranging
(lidar) data. In this study, a pair of digital surface models (DSMs)
obtained from the high-density lidar data before and after the mainshock on
16 April 2016 were used. A window matching search approach based on the
correlation coefficient between the two DSMs was used to estimate the
geodetic displacement in the near-field region. The results showed good
agreements with the geodetic displacements calculated from strong-motion
acceleration records and coincided with the fault line surveyed by the
Geological Survey of Japan.
