Lombok Island, in West Nusa Tenggara (NTB), is located on the active tectonic area, surrounding by the sources of earthquake which have potential to create shocks, such as Back Arc Thrust at the north region, megathrust at the south area, and sliding fault system at west and east region, therefore, Lombok Island has high earthquake potential. Some of the earthquake are destructive, such as the earthquake incident on July 29, 2018 (6.4 Mw), August 5 (7 Mw), August 9 (6,2 Mw) and August 19 (6,9 Mw) in Lombok. This research is conducted to give information regarding the size of sliding or movement of earth surface which caused by some series of Lombok earthquake by using DInSAR (Differential Interferometry Synthetic Aperture Radar) technology from 6 satellite imageries Sentinel-1 on July 2018 and August 2018 , also DEM SRTM 30meter. As the result of InSAR, indicate that generally, the change of earth surface impacted by the series of Lombok earthquake is uplift at the north coast area with cumulative result reached around 40 cm, but also has subsidence which detected at the east and west coast area at around 3 cm.
