Bridging Consecutive DInSAR Method for Long Term Land Deformation Observation

Previously, many researchers have developed various methods to observe land subsidence in the Sidoarjo area using synthetic aperture radar (SAR). This research proposed the equation to estimate the current and volume of outflow of hot mud in the study area using various SAR missions and a Bridging Consecutive DInSAR (BC-DInSAR). The analysis result of the proposed techniques was validated using differential GPS (DGPS) and acquired an accuracy of 0.46 m.
