Magnitude versus a hypocenter or rupture distance and b PGA of the strong-motion records used in this study. The hypocenter distance is used for aftershocks, and the rupture distance (shortest distance between the station and rupture surface) is used for the main shock, which is calculated according to the fault slip model provided by the USGS. The vertical dashed line is the boundary between strong and weak motions defined in this study
