| 摘 要： | 阐述了张北－尚义地震的区域地震构造环境，结合本次地震的宏观烈度分布、震源机制解和震区卫星影像的线性构造解释等资料，讨论了地震的孕震构造和可能的发震断层，认为本次地震是张家口－蓬莱断裂带北西端最新活动的结果，北西向的张家口－蓬莱断裂带未来的地震活动趋势应引起重视

SEISMOTECTONICS AND MACRODAMAGE FEATURES OF THE ZHANGBEI SHANGYI EARTHQUAKE |
| |
| Abstract: | he regional seismotectonic environment of the Zhangbei Shangyi earthquake is stated in detail together with its seismic intensity distribution, co seismic ground fissures, focal mechanism solutions and interpretation of linear structures on the MSS satellite images around the epicenter. Its possible seismogenic fault or structure is also discussed. It is suggested that this earthquake was resulted from the most recent abrupt slip on a NNE trending fault at the northwestern termination of the Zhangjiakou Pe |
