Abstract

This paper described the application of Sentinel-1 TOPS (Terrain Observation by Progressive Scans) SAR (Synthetic Aperture Radar) to analyze the surface deformation of the Agung Volcano due to 2017-2018 eruption. Agung volcano is an active stratovolcano located in eastern part of Bali island. We processed the interferometric from a pair of Sentinel-1A each representing before and after eruption periods. The results of this research showed that the eruption of Agung Volcano during 2017-2018 has caused surface deformation. The deformation that occurs was related to changes in land surface due to lava and pyroclastic deposits resulting from the eruption process in the area around the crater and the northern slope.
