| 摘 要： | 使用地震和地质资料的综合分析方法研究了腾冲一勐海地区地震破裂特征,结果认为:本区存在长400km,宽45km的地震构造带,它是由一条长400km,宽25km的NNW向右旋剪切带为主干和几条NE-NEE向左旋走滑断裂变切而成的共轭地震构造带.带内地震具有线性排列和统一的周期性活动.

| Abstract: | In this paper, we studied the seismic rupture characteristics in the Tengchong - Menghai region with the comprehensive analysis of the seismic and geologic data. The result shows that a 40km long, 45km wide conjugate seismotectonic zone exists in this region, which consists of one 400km long, 25km wide NNW right lateral shear zone and several crossing left lateral strikeslipe faults. The earthquakes inside the zone showed linear arrangements and have unified period activities. |
