| Abstract: | Corresponding the seismogenic process of Wuding,Lijiang,Ninglang and the like earthquake in Sichuan and Yunnan and by use of the deformation tide observations in the radius of 100 km to their epicenter the short impending tilt and horizontal strain variation patterns and the deformation characters of tide in the process of dilatancy and seismic nucleation are studied.In addition,the relation between the relative tidal factor variation and crustal elastic parameter variation is analyzed. |
