N2 - Land subsidence in the Bandung basin, West Java, Indonesia, is characterized based on differentialinterferometric synthetic aperture radar (DInSAR) and interferometric point target analysis (IPTA). Wegenerated interferograms from 21 ascending SAR images over the period 1 January 2007 to 3 March 2011.The estimated subsidence history shows that subsidence continuously increased reaching a cumulative45 cm during this period, and the linear subsidence rate reached ~12 cm/yr. This significant subsidenceoccurred in the industrial and densely populated residential regions of the Bandung basin where largeamounts of groundwater are consumed. However, in several areas the subsidence patterns do not corre-late with the distribution of groundwater production wells and mapped aquifer degradation. We concludethat groundwater production controls subsidence, but lithology is a counteracting factor for subsidencein the Bandung basin. Moreover, seasonal trends of nonlinear surface deformations are highly relatedwith the variation of rainfall. They indicate that there is elastic expansion (rebound) of aquifer systemresponse to seasonal-natural recharge during rainy season.
