    Abstract

    In order to estimate recent surface displacement in Bangkok, we applied persistent SAR interferometry using ALOS/PALSAR images acquired October 2007 to December 2010. Previously, land subsidence due to excessive ground water pumping has been reported in this region. However, we detected that ground surface has rebounded during 3 years of the observation period. This rebounded surface can be interpreted as the response on the ground water recovery to confined aquifer due to the decrease in ground water usage. Since the rebounded areas correspond to past ground subsidence areas inferred from differential SAR interferometry using JERS-1/SAR images, it can be inferred that ground water recovery has especially occurred at the preceding subsidence areas.
