AB - In this study we will review potential and gravity gradient changes due to Sumatra’s 9.2-magnitude earthquake on 26th Dec 2004 using data collected from GRACE Satellite. The gravity gradients clearly show the variations of mass distributions in the ground. The previous studies have shown that filters and softening algorithms were used to elimination of stripe error of GRACE observations. In this study we find the application of gravity gradient in removing stripe error of observation of GRACE satellite and we see that with these gradients in direction, gradient tensor components such as and cause eliminate GRACE observations strip errors however with these gradients in direction, gradient tensor components such as and would cause fluctuations to intensify in north-south direction. Also we find the maximum and minimum value of gravity gradient changes (1.5mE and -1.2mE) will be earned in direction.
