Abstract: In recent years, the rapid development of satellite geodesy provides unprecedented multidimensional observations for the accurate measurement of crustal deformation and fault behavior. Combined with seismology, the temporal and spatial resolution of earthquake cycle deformation monitoring is greatly improved, which provides a chance for further study of earthquake cycle process and mechanism. Seismogeodesy can quantitatively describe the crustal movement and accurately model the fault activity. It can also provide a scientific basis to understand the stress and strain evolution of the whole earthquake cycle process, and provide scientific guidance for the assessment of seismic hazard and earthquake prediction and early warning. This paper analyzes the kinematic characteristics of faults at different stages of the earthquake cycle, including interseismic, coseismic, and postseismic, and reviews some important findings of seismic geodesy in terms of source physics by using satellite geodetic observations to investigate fault deformation. The satellite geodetic data can be applied to determine the fault location in the stage of earthquake cycle. It is a feasible idea for earthquake prediction.
