ANALYSIS OF TILT TIDE CHARACTERISTICS AND THEIR DYNAMIC COMBINATION IN FUJIAN
福建地倾斜固体潮特征及其动态组合分析

The tidal factors from the EW and NS components of ground tilt in Fujian from 1990 to 2004 are calculated. The full-time plots for the characteristic quantities (dilatancy, shearing strain, media anisotropy) are drawn and their relations with mid-strong 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.
