Abstarct: The gravity measured at a specific point in addition to the mass factor and mass distribution of Earth crustal ingredients, is dependent on other factors such as elevation change, mass transfer, and geographic changes. Satellite Gravity data is such as Terrestrial and atmospheric data by affected various factors. The existence of a GRACE twin satellites, which has the ability to repeated and retrieve data within a month for the entire earth, has Ability of mapping from changes the Earth's Gravity field. Time variations of the gravitational field due to mass changes due to factors such as the occurrence of large earthquakes, the melting of polar ice, the displacement of seawater levels and ocean currents, and changes due to the movement of groundwater level can be detected by GRACE. In this study, using GRACE satellite data, Gravity field changes and geoid levels changes In effect to the occurrence of three major earthquakes Sumatra-Andeman earthquakes in Indonesia (2004), Maul in Chile (2010) and Tohoku in Japan (2011) in the last 15 years have been investigated. For this purpose, GRACE satellite data was corrected by applying different filters. Then, to estimate the location of the earthquake, the changes in the field of gravity were calculated and plotted. By analyzing these maps, the status of large faults can be checked. By calculating mass changes in terms of the thickness of the equivalent water laxyer using satellite observations and also with the aid of the GLDAS hydrologic model, the underground water level changes have been evaluated. Depending on the type of satellite mapping, the effect of striping appears on the maps. Three different Gaussian, Fan, and destriping filters were used to better detected the changes in the Gravity field and to remove strip errors and to eliminate possible noise in the GRACE data. Land data to reclaim groundwater level changes have high power and high resolution power toward GRACE data, but the results of gravity satellite data provide an acceptable map after applying these filters.
