BASIN EDGE EFFECT ON GROUND MOTION FROM HYOGO-KEN NANBU EARTHQUAKE IN THE KOBE REGION

| 抄録（英）： |
We model the ground motion from the mainshock of the 1995 January 17 Hyogo-ken Nanbu earthquake to investigate basin edge effects on wave propagation in the Kobe region. The kinematic earthquake rupture and the wave propagation are modeled using a 3D finite-difference method. Our simulation identifies the basin edge effect as an important factor that influenced the ground motion amplification pattern in the Kobe area. We found that the coupling of the source directivity and basin edge effects causes impulsive ground motions with extremely high amplitude at periods greater than 1s. The combination of these effects acted to create a fairly continuous band of amplification which extends in an elongated zone parallel to the basin edge boundary.
