SummaryThe main research objectives of our group are the monitoring of geodynamic processes related to geothermal, seismic, and volcanic activity and of climate change in the highly active Neovolcanic Zone of Southern Iceland by means of TerraSAR-X data. The ultimate goal is the establishment of an SAR based operational monitoring service to be employed for risk assessment, early prediction and damage mitigation. Due to our various research projects on disaster monitoring in Iceland, carried out under the auspices of ESA, NASDA and CSA since 1992, we can access a substantial collection of multi-sensor SAR data sets (C-, L-Band) over the test sites is at the disposal for the new TerraSAR-X project. The observations are focusing on three test sites in South Iceland where special infrastructure, like Corner Reflectors, has been installed: the central volcano Hekla, the plateau glacier Mýrdalsjökull with the subglacial Katla Caldera and the Vatnajökull ice cap covering several fissure swarms and central volcanoes. The 1996, 1998 and especially 2004 subglacial eruptions with its adjected huge glacial torrents in Iceland and future events during TerraSAR-X lifetime are to serve as a case in point to evolve effective methods for observing natural disasters and assessing the magnitude of their impact. Special research objectives are the observation of glacier dynamics (uploading/deloading) and their effects on subglacial volcanoes (external triggering), and the surveillance of areas threatened by meltwater drainage following subglacial outbreaks. Verification of the findings by ground truth involving the determination of surface roughness, geologic, geomorphologic, glaciologic and hydrogeologic studies will be a main focus.
