| Abstract: | After analyzing the original data recorded by Type-FSQ float water piper from Midu,Yongsheng and Chuxiong three stations, and Type-JB metal pendulum tiltmeter from Gejiu station, the author picked out the abnormal patterns on deformation characteristics that appeared just before Lancang-Gengma great shock and later comparied these patterns with rock mass deformation in focal regions. Also the author made an approach on the mechanism and process of seismogenic varying body. |
