摘要
对应 1993~ 2 0 0 1年间川滇地区的武定、丽江、宁蒗等强震孕育过程 ,应用距离震中 10 0km范围内的形变潮汐观测资料 ,研究了倾斜、水平应变短临变化图像和该区域形变潮汐在扩容、地震成核过程中的特征 。
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.
