Abstract
An earthquake of MJMA 6.6 occurred in the central part of Tottori prefecture in Japan on October 21, 2016. Recorded JMA seismic intensity were 6 lower at three observation points. Serious damages were concentrated in partial areas. Aftershock observations were conducted at damaged area to clarify causes of the damage. In this study, we evaluated strong ground motions at aftershock observations points using empirical Green's function method. It was found that damaged sites tend to have high peak ground velocity and high response values in period range around 1.0sec.
