| Abstract: | The tidal strain observations, which are closely related to earthquake preparation process,are chosen and extracted.Using the analysis method of residual vector in tidal observation, the residual vector variations of the tidal line strain, plane strain and shear strain observations in Lancang-Genma, Tianzhu-Jingtai and Datong-Yanggao earthqake processes are analyzed. |

| Keywords: | tidal deformation residual error strain crustal deformation precursor |
