摘    要:本文对川滇地区中、强震震源机制解和中小地震平均节面解分析,指出川滇地区现今构造应力场在北西-北西西向压应力作用下,以水平剪切错动为主。同时,采用极值理论、最大信息熵、线性预测和灰色理论等方法综合分析,预测川滇地区未来强震的趋势。

关 键 词:构造应力场 地震 强震 统计预测

Abstract:In this paper, we analysed the earthquake focal mechanism of strong-moderateearthquake and the mean plane solution of moderate-small earthquake in the area whereSichuan and Yunnan meet.We consider that the horizontal shear dislocation is major and thecurrent structural stress-field is controled by the pressure stress in NW-NWW.Simultaneously,we comprehensively analysed and predicted the trend of strong earthquake inthe area using extremal theory,maximum information entropy,grey theory and so on.
Keywords:maximum principle stress  extremal model  maximum entropy spectrum analysis  grey theory  strong earthquake  trend prediction.
