Abstract The tidal factors from the EW and NS components of ground tilt in Fujian from 1990 to 2004
are calculated. The fulltime plots for the characteristic quantities (dilatancy, shearing strain, media anisotropy) are drawn and their relations with midstrong earthquake are analyzed. The results show that the ocean tide is a main factor to determine the characteristics of tilt tide in the shore area of Fujian and the dynamic combination characteristic quantities of tilt tide correspond to Fujian earthquake (M＞4.5) or Taiwan earthquake (M＞7.0) well.
Key words ：
crustal deformation
ground tilt
tidal factor
characteristic quantily
