Digital elevation models of glaciated terrain produced by the NASA/Jet Propulsion Laboratory (JPL) airborne interferometric synthetic-aperture radar (InSAR) instrument in Greenland and Alaska at the C(5.6 cm wavelength) and L-band (24-cm) frequencies were compared with surface elevation measured from airborne laser altimetry to estimate the phase center of the interferometric depth, or penetrat...

a r t i c l e i n f o Multi-temporal interferometric synthetic aperture radar (InSAR) is an effective tool to detect long-term seismotectonic motions by reducing the atmospheric artifacts, thereby providing more precise deformation signal. The commonly used approaches such as persistent scatterer InSAR (PSInSAR) and small baseline subset (SBAS) algorithms need to resolve the phase ambiguities i...

Intensive and large-scale underground coal mining has caused geological disasters such as local ground subsidence, cracks collapse in the Datong coalfield, China, inducing serious threats to residents. Interferometric synthetic aperture radar (InSAR) capability of surface deformation detection with high precision vast mountainous areas. DInSAR, stacking-InSAR SBAS-InSAR are commonly used InSAR-...

This paper describes an automatic mosaicking algorithm for creating large-scale mosaic maps of forest height. In contrast to existing mosaicking approaches through using SAR backscatter power and/or InSAR phase, this paper utilizes the forest height estimates that are inverted from spaceborne repeat-pass cross-pol InSAR correlation magnitude. By using repeat-pass InSAR correlation measurements ...

S U M M A R Y We present a semi-analytic iterative procedure for evaluating the 3-D deformation due to faults in an arbitrarily heterogeneous elastic half-space. Spatially variable elastic properties are modelled with equivalent body forces and equivalent surface traction in a ‘homogenized’ elastic medium. The displacement field is obtained in the Fourier domain using a semi-analytic Green func...

This study investigates the options of information mining to enhance interpretation of PS-InSAR results of land subsidence analysis. Persistent Scatterer (PS) Interferometric Synthetic Aperture Radar (InSAR) is one of the latest applications of SAR time series data analysis. The detection of coherent point target measurements i.e, persistent scatterers gives an opportunity of measuring sub-cm d...

Volterra (Central Italy) is a town of great historical interest, due to its vast and well-preserved cultural heritage, including a 2.6 km long Etruscan-medieval wall enclosure representing one of the most important elements. Volterra is located on a clayey hilltop prone to landsliding, soil erosion, therefore the town is subject to structural deterioration. During 2014, two impressive collapses...

a r t i c l e i n f o Keywords: InSAR Multi-temporal InSAR Subsidence Aquifer Fault Oil field Salt dome Houston Houston–Galveston (HG) region in Texas has been subsiding due to the combined effects of groundwater withdrawal , hydrocarbon extraction, salt dome movement, and faulting. This human-and partially nature-induced ground deformation has gradually threatened the stability of urban infras...

Satellite interferometric synthetic aperture radar (InSAR) has proven to be an effective tool for monitoring surface deformation from volcanoes, earthquakes, landslides, and groundwater withdrawal. This paper seeks to expand the list of applications of InSAR data to include monitoring subsidence possibly associated with thaw settlement over the Alaskan Arctic Coastal Plain. To test our hypothes...
