Abstract

Abstract: The physical sense of dynamical geoid is discussed and the patterns of local geoid changes due to several faulting dislocations are studied by using the numerical analysis method. The relation between fault dislocations and geoid changes is emphatically studied. Moreover, the geoid changes caused by dilatancy are also studied. At last , the possibility to monitor local geoid changes of seismogenic zone in the fields of sea and seashores by means of tide-gauge observation, satellite altimetry and radar altimetry is deeply discussed and it is thought that the means is of very impotent significance in monitoring and predicting earthquakes.

Key words: Dislocation, Geoid, Dilatancy, Earthquake monitoring
