讨论了与１９９５年１月１７日日本兵库县南部７．２级地震相应的余震及灾害的分布、内陆直下型地震的发生与断层的关系及强震动等基本特征．地表断层系同地下断层系的构造可能存在着较大的差异，地震不一定受既存活断层系（地表断层系）构造活动的制约，强震动域不与震源断层位置直接相对应，而多出现于稍偏离断层两端的区域或断层单侧稍远处的区域内．对强震动的机理也进行了一些探索性的讨论 This paper discusses the distribution of aftershocks and disasters corresponding to the magnitude 7.2 earthquake in southern Hyogo, Japan on January 17, 1995, the relationship between the occurrence and the fault of an inland straight type anomaly, and strong vibrations. There may be large differences between the surface fault system and the underground fault system. The earthquake is not necessarily controlled by the tectonic activities of the existing fault system (surface fault system). The strong earthquake motion field does not directly correspond to the focal fault location, In areas slightly offset from the two ends of the fault or in areas slightly further to the side of the fault. The mechanism of strong vibration is also discussed in some exploratory ways
