Land subsidence in the Bandung basin, West Java, Indonesia, is characterized based on differential
interferometric synthetic aperture radar (DInSAR) and interferometric point target analysis (IPTA). We
generated 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 cumulative
45 cm during this period, and the linear subsidence rate reached ∼12 cm/yr. This significant subsidence
occurred in the industrial and densely populated residential regions of the Bandung basin where large
amounts of groundwater are consumed. However, in several areas the subsidence patterns do not correlate
with the distribution of groundwater production wells andmapped aquifer degradation.We conclude
that groundwater production controls subsidence, but lithology is a counteracting factor for subsidence
in the Bandung basin. Moreover, seasonal trends of nonlinear surface deformations are highly related
with the variation of rainfall. They indicate that there is elastic expansion (rebound) of aquifer system
response to seasonal-natural recharge during rainy season.
