Monitoring and characterization of land subsidence of the Bandung basin, Indonesia has been carried out based on Synthetic Aperture Radar (SAR) data acquired by ALOSPALSAR satellite for the period of 1 January 2007 — 3 March 2011. Estimated subsidence continuously increased up to around 45 cm at a rate of about 12 cm/yr for this period. The land subsidence occurred in the industrial and dense-residential regions in the Bandung basin where large amounts of groundwater were consumed. Interestingly the subsidence patterns are uncorrelated to the distribution of groundwater production wells and the map of aquifer zonation in several areas. We concluded that the subsidence expansion not only depended on groundwater production but also was controlled by lithology over the Bandung basin.
