a PGA of seismic records logged at IBRH13. The horizontal dashed lines represent 50, 200 and 400 cm/s2, respectively, and the gray areas represent the influence time of strong motions. b Daily rainfall for IBRH13. The horizontal dashed lines represent 25, 50 and 100 mm, respectively. The zeroth day of the horizontal axis indicates the start date when sampling frequency of seismographs at IBRH13 is changed to 100 Hz (17 October 2007)
