Abstract

InSAR has been proved to be a reliable technology for detecting surface displacements caused by earthquakes, underground mining, groundwater extraction, and other geophysical and engineering processes. Compared to other geodetic technologies such as leveling and GPS, InSAR is more advantageous in inferring spatially continuous surface deformations due to its wide spatial coverage. However, InSAR applications have been severely limited by decorrelation, especially for short wavelength (e.g. C-band) SAR data. In this paper, we investigate the capability of L-band ALOS PALSAR data in detecting land subsidence or uplift ober Southern California, USA. The results from PALSAR data are analyzed in comparison with those from C-band ENVISAT ASAR data. In addition, GPS results over the area from the Southern California Integrated GPS Network (SCIGN) are used to validate the results. The research shows significant improvements of the L-band results over the C-band ones and reveals the magnitudes of displacements over the area during 15 February 2007-20 February 2009.
