摘要
基于水口水库区历史地震活动特征,探讨水口水库地震的序列特征;对库区短水准地形变资料及震源机制解结果的分析认为,水口水库区的地震活动前期主要为水的诱发作用,后期与构造应力场作用加强有关。
On the basis of characteristics of historical earthquake of the Shuikou reservoir area the feature of the earthquakes in the Shuikou reservoir area is discussed. Through the analysis of the crust deformation data observed by short-line leveling and the resuhs of focal mechanism resolution, it is proposed that in the earlier stage of the seismicity in this area was induced by water and in the later stage it is related to the tectonic stress field strenthening.
