FIGURE 3.24 Settlement and tilting of relatively light buildings
located in Niigata, Japan. The buildings suffered liquefaction-
induced settlement and tilting during the Niigata earthquake on
June 16, 1964. ( Photograph from the Steinbrugge Collection,

● Ground rupture due to the right-lateral strike-slip faulting was observed on Awaji Island,
which is located to the southwest of the epicenter. In addition, the Akashi Kaikyo Bridge,
which was under construction at the time of the earthquake, suffered vertical and lateral
displacement between the north and south towers. This is the first time that a structure of
this size was offset by a fault rupture.
● Peak ground accelerations as large as 0.8 g were recorded in the near-fault region on allu-
vial sites in Kobe.
● In terms of regional tectonics, Kobe is located on the southeastern margin of the Eurasian
plate, where the Philippine Sea plate is being subducted beneath the Eurasian plate (see
Fig. 2.1).
● More than 5000 people perished, more than 26,000 people were injured, and about $200
billion in damage were attributed to this earthquake.
