摘要
本文依据大量地震资料,阐述了青藏高原地震的空间分布规律和构造应力场特征.强震活动主要分布在高原周围边缘地带;震源深度以浅源为主,中源地震较多,无深源地震;构造应力场主压应力优势方向为NNE-SSW.
In this paper,the spatial distribution low of earthquakes and characteristics of the recent tectonics of the recent tectonic stress field here been descussed. It shows that large earthquakes distribute mainly around borders; they are shallow-intermediate focused. The main compressive stress directions of tectonic field are NNE-SSW.
