Landslide is one type of slope movement, which includes creep. Although the creep movement does not impact the risk of loss of life, this creep movement takes place constantly and is invisible, affecting economic losses. In this study, a time-series monitoring was carried out from 2018 to 2020 to see the movement of the slopes in the study area using the Multi-Temporal Interferometry Synthetic Aperture Radar (MTInSAR). A time series method from Sentinel 1A/B data, which includes Trangkil Sejahtera Housing (PTS), Soegijapranata Catholic University (UNIKA), and 17 August 1945 University (UNTAG) in Semarang City, Indonesia. The data processing results indicate that there are slope movement in the target location, namely Trangkil Sejahtera and Selorejo Housing (southwest of UNIKA). Based on BPBD 2021 data, landslides occurred in the Trangkil Baru Housing Center (to the north of PTS) and the Garang River landslide channel west of Selorejo. This shows a link between crawling in 2018-2020 and landslides in 2021. Although satellite data has some drawbacks, the results can be taken into consideration in building an early warning system and reducing losses due to landslides.
