9614757 Anderson This research involves the study of the January 17, 1995, HyogoKen Nambu earthquake (Mw=6.9), commonly referred to as the Kobe earthquake in the United States. The earthquake was particularly destructive because the fault ruptured into a densely developed urban area. This is to be an integrated study of the factors that controlled the nature of the ground motions and caused the disaster: the earthquake source, wave propagation along the path, and near-surface modification of these motions at nearsurface sites. The area affected by the earthquake was well instrumented for strong ground motion. The earthquake focal mechanism was predominantly strike slip. Thus, the ground motions may be analogous to what should be expected from earthquakes of this size on strike-slip faults such as the San Andreas in the United States. The work will be done in collaboration with Japanese scientists at the Disaster Prevention Research Institute, Kyoto University, in Japan. This research is a component of the National Earthquake Hazard Reduction Program. ***

9614757安德森这项研究涉及1995年1月17日兵库县南部地震（Mw=6.9）的研究，通常被称为美国的科比地震。 这次地震的破坏性特别大，因为断层破裂进入了一个人口稠密的城市地区。 这是一个综合的研究因素，控制的性质，地面运动和造成的灾难：震源，波传播沿着路径，和近地表修改这些运动在近地表网站。 受地震影响的地区有很好的监测强烈地面运动的仪器。 震源机制以走滑为主。 因此，地面运动可能类似于在走滑断层（如美国的圣安德烈亚斯）上发生的这种规模的地震。 这项工作将与日本京都大学防灾研究所的日本科学家合作完成。 这项研究是国家地震减灾计划的一个组成部分。***
