چکیده

The Mw 7.3 1995 Aqaba earthquake is the largest instrumental earthquake along the Dead Sea Fault. We complement previous seismological studies by analyzing co-seismic ground displacement from differential interferometry computed from ERS images spanning 3 different areas. They are compared with a synthetic model derived from seismological study. Only far-field deformation related to the main sub-event could be revealed because the near-field area lies within the gulf. The interferometric data imply a 56 km long and 10 km wide fault segment, connecting the Elat Deep to the Aragonese Deep, which strikes N195°E and dips 65°to the west, with 2.1 m left-lateral slip and a 15.5°rake indicating a slight normal component. The geodetic moment compares well with the seismic mo-

D-InSAR Research at IIT Bombay - Simulation Experiments Synchronous with ERS 1/2 Tandem Passes

During tandem period of ERS-1/2 (April June 1996), field experiments were conducted in Bhavnagar test site with Corner Reflectors (CRs) to study the sensitivity of differential SAR interferometry to estimate the movements of CRs. Initially, three images acquired on April 4, 5 and May 9, 1996 were processed to generate interferograms. Using single interferogram formed with April 4 and May 9, dur...

European Forest Mapping with SAR Interferometry

Forest maps of three European regions were completed with ERS SAR interferometry. The test-areas are Bern (Switzerland), Lozère (France), and Tuusula (Finland), representing different European forest types and topographic regions. The mapping algorithms used were similar in all cases and well suitable for forest observation. In this contribution the methodology applied and the results achieved ...

Land Subsidence Monitoring with Differential SAR Interferometry

The potential of differential SAR interferometry for land subsidence monitoring is reported on. The principle of the technique and the approach to be used on a specific case are first presented. Then significant results using SAR data from the ERS satellites for various sites in Germany, Mexico, and Italy, representing fast (mlyear) to slow (mmlyear) deformation velocities, are discussed. The S...

On the exploitation of the SBAS Algorithm for the analysis of the deformations detected from the ERS and ENVISAT DInSAR data

We present a Differential Synthetic Aperture Radar Interferometry (DInSAR) technique for generating displacement maps and deformation time-series by exploiting the SAR data acquired by the ERS and ENVISAT/ASAR systems. The proposed approach extends the Small Baseline Subset (SBAS) algorithm and is based on an easy but effective combination of ERS/ERS and ENVISAT/ENVISAT multilook interferograms...

Monitoring of Deforestation in Tropical Rain Forest Areas by Using Insar - Comparison between L-band and C-band Sar -

ABSTRACT: The author compared the capability of coherence information obtained from interferometric SAR (InSAR) by C-band SAR of ERS-1 and 2 and by L-band SAR of JERS-1 for the purpose of monitoring the changes of tropical rain forest due to deforestation. The test site was a southern part of Sumatra Island with 50 by 50 kilometers coverage. The several repeat-pass interferometric data pairs by...

Land Subsidence Mapping with Ers Interferometry: Evaluation of Maturity and Operational Readiness

Differential SAR interferometry with ERS data has a high potential for surface displacement mapping in the mm to m range. Such displacement information is of interest for the monitoring of phenomena as land subsidence, land slides, earthquakes, volcano swelling, and ice motion. In this contribution the maturity and operational readiness of the SAR interferometric technique are discussed, focusi...
