Monitoring crustal movements is important in understanding the earth surface and in developing theories about plate tectonics. Plate tectonics describes earth crust which consists of a number of plates moving relative to one another. Global plate models suggest that plate movements are constant due to the fact that relative movements of plates were represented by averaged plate motion. However, if an earthquake occurs, the uniform movement of related plates does not follow the regular trend. In analysis by Kalman Filter, the effects of an earthquake occurred within crustal movement monitoring period by geodetic method have been eliminated by a proposed approach, Fading Memory Filter. The proposed method was tested using a real/simulated data. The results of the test showed that the effect of a strong earthquake (M-W = 7.1) which had occurred in the Gulf of Eilat/Aqaba was eliminated. Consequently, the proposed method is capable of removing or eliminating a sudden effect in monitoring crustal movements in the analysis by using the Kalman Filter.
