摘    要:在本研究的前一项工作中,根据WWSSN的长周期无震体波记录,采用广义反演技术,确定了1966年至1980年期间发生在西藏高原及其周围地区的11个主要地壳地震和地震矩张量,同时得到了震源时间函数和震源深度。所分析的地震具有较浅的震源深度,且均分布于上部地壳范围内,本文根据上述结果,结合其它逐个测定的1964年至1986年发生在青藏高原的78个中强地震的震源深度的结果,讨论了青藏高原地震的震源深度分布

关 键 词:青藏高原  震源深度  构造意义  地震  地震地质

Abstract:In the previous work of the present study, moment tensors of eleven major earthquakes in the Tibetan Plateau and its surrounding region from 1966 to 1980 are estimated by generalized inverse technique. The seismic source time function and focal depth are immediately determined in the inversion. The result indicated that all earthquakes investigated here are shallow events located within the upper crust. The purpose of this paper is to present a summary of the distribution of focal depths of earthquakes in and near the Tibetan Plateau from the above result, combining the focal depths of 78 significant Tibetan earthquakes from 1964 to 1986, which are relocated individually by other authors, as well as to discuss its tectonic implication.
Keywords:Tibetan Plateau  Focal depth  Tectonic implication
