EXTENDING THE TEMPORAL COVERAGE OF ICELANDIC CRUSTAL DEFORMATION MEASUREMENTS THROUGH ENVISAT InSAR IMAGES 1
Iceland has for decades been an international target for geodetic studies, as it provides opportunity to study a wide variety of crustal deformation processes, including plate tectonics, magmatism, and responses of the crust due to load variations. We here present results from crustal deformation su...

Iceland has for decades been an international target for geodetic studies, as it provides opportunity to study a wide variety of crustal deformation processes, including plate tectonics, magmatism, and responses of the crust due to load variations. We here present results from crustal deformation surveillance spanning 2003-2006, obtained from interferometric processing of ASAR ENVISAT images, contributing to an extension of the time series of ongoing deformation processes in Iceland. More than 100 ASAR interferograms (ha>50 m), have been produced so far, spatially covering the entire neotectonic zone. The interferograms show three areas of significant deformation. Hekla and Askja volcanic systems continue to deform in a similar manner as observed with ERS interferometry 1992-2000. At the Krafla volcanic system subsidence due to processes in a shallow magma chambers appears to have stopped, while other processes related to plate spreading and possible deep accumulation of magma continue. 1. |
