摘要
据两种关系,即1812年尼勒克8级地震产生的地表破裂与断裂破裂的对应关系和地震最高烈度与破裂延伸烈度区间的关系,同时考虑古地震研究成果和现代地震活动特征,对喀什河断裂带进行了破裂分段性研究,将喀什河断裂带以博尔博松为界分为东、西两段,东段长220 km以上,西段长290 km。研究表明,东段目前处于1812年尼勒克8级地震以后的地震活动相对平静期,在未来的时间里喀什河断裂带西段可能是大震活动的主要区段。
The rupture subsection of Kashi River fault zone is investigated mainly based on two relations. They are the corresponding between the rupture of the faults and the earths surface rupture of Nilka M 8 earthquake in 1812 and the relation between the highest intensity of earthquake and the extending intensity region. Simultaneously we consider the study of paleoseismology and the feature of modern earthquake activity. Kashi River fault zone is divided into west and east segment, Boerbosong as the boundary. The west is about 290 km long and the east is more than 220 kin. The study indicates that the east is in relatively quiet period and the west may be the main section of large earthquake in the future.
