摘要
通过可可托海─阿克塞测深大剖面获得的地壳结构、深部资料结合地震活动进行分析,认为:地震与深断裂活动有关,与地下10~40km深的速度异常层有关,地震一般发生于波速突变的相对低速层中。
According to the analysis of deep-crustal structures and seismicities in the northern part of Koktokay-Aksay deep sounding profile, it is considered that earthquakes are correlated with both the deep-seated fractures and the abnormal layers of wave velocity 10~40km deep beneath, and generally they often generate and occur on the relative low speed layers in which wave velocity changed suddenly.
