Ground deformation associated with the March 1996 earthquake swarm at Akutan volcano, Alaska, revealed by satellite radar interferometry
In March 1996 an intense swarm of volcano-tectonic earthquakes (-3000 felt by local residents, A/max5.1, cumulative moment of 2.7 x 10 •8 N m) beneath Akutan Island in the Aleutian volcanic arc, Alaska, produced extensive ground cracks but no eruption of Akutan volcano. Synthetic aperture radar interferograms that span the time of the swarm reveal complex island-wide deformation: the western pa...

متن کاملMapping Ground Deformation by Radar Interferometry Based on Permanent-scatterer Network: Algorithm and Testing Results
The full operational capability of synthetic aperture radar (SAR) interferometry in deformation monitoring has not been achieved yet due to the negative influences of spatio-temporal decorrelation and atmospheric delay. With the use of time series of SAR images, deformation extraction can be however improved by only tracking some objects with steady radar reflectivity, generally referred to as ...
متن کاملProspects of Volcano Geodesy with ERS Radar Interferometry
Since the detection of surface deformation at Mt. Etna it was believed that space-borne radar interferometry may provide a tool to monitor most of the Earth's active volcanoes. We have studied a large number of volcanoes from different environments and show that ERS C-band radar interferometry can be used only to observe certain volcanoes with particular conditions. The best targets for ERS C-b...
متن کاملIntegrated Radar Interferometry for Ground Subsidence Monitoring
This paper reports the progress of the ongoing ESA CAT-1 project (ID 1078). Radar interferometry (InSAR) has been used together with GIS (Geographic Information System) technique to monitor ground subsidence due to underground mining in a test site around the Appin township, southwest of Sydney, Australia. Various digital elevation models (DEMs) are assessed using elevation profiles from ground...
