邢台老震区地震构造环境特征

CHARACTERISTICS OF SEISMOTECTONIC ENVIRONMENT IN OLD XINGTAI EARTHQUAKE AREA

由于地震构造环境是有机的整体,需要结合岩土水热构造带进行综合考虑,对1986年以来邢台老震区的相关研究进行系统总结,结合老震区分层,包括盖层,基底和震源层,研究邢台7.2级地震的构造环境。邢台7.2级地震烈度线形态特征和新构造格局有一定关系,地震构造环境对蠕滑地裂缝产生影响。

As the seismotectonic environment is an organic whole,it is necessary to comprehensively consider in combination with the geotechnical hydrothermal structural belt,systematically summarize the relevant studies in the old seismic area of Xingtai since 1986,and study the tectonic environment of Xingtai M_(S)7.2 earthquake in combination with the stratification of the old seismic area,including caprock,basement and focal layer.The morphological characteristics of the intensity line of Xingtai M_(S)7.2 earthquake are related to the neotectonic pattern,and the seismic tectonic environment can also have an impact on the creep ground fissures.
