Anak Krakatoa Volcano is a young volcano that appeared in the caldera after the proximal eruption in 1883 from the Krakatoa volcanic complex. currently, Anak Krakatoa Volcano is in the construction phase. Based on measurements by the Center for Volcanology and Geological Hazard Mitigation (PVMBG) conducted in September 2018, it was found that the elevation of the Anak Krakatoa volcano is above 338 m from sea level. From June 25, 2018, until the end of 2019 Anak Krakatoa Volcano experienced a strombolian eruption, this eruption caused deformation on the surface of the Volcano. The research used the Differential Interferometry Synthetic Aperture Radar (DInSAR) method with Sentinel-1A image data from April 2018 to December 2019 which was further validated using volcanic activity released by PVMBG. The results were obtained in the form of deformation value based on Line of Sight (LOS) displacement, and the result of deflation is 0,01 cm to 17,1 cm using cross-section in the area around the crater is deflation in June 2018 to February 2019.
