较大的地震活动带和正在活动、发展的深大断裂密切相关。尤其是在多组活动断裂交汇、分叉、拐弯以及断层尚在发展,断层断断续续尚未沟通的地方,往往是大地震发生的部位。找出这些部位判断其活动状况,有助于地震预报的研究。就是在一些 The larger seismic activity zone is closely related to the deep faults that are active and developing. Especially in the intersection of multiple sets of active faults, bifurcation, cornering and the fault is still developing, the fault has not yet communicated intermittently, often the site of a major earthquake occurred. Finding these parts to judge their activities is helpful for the study of earthquake prediction. It is some
