SummaryThe main objectives of our research are the monitoring of geodynamic processes related to volcanic, geothermal and seismic activity in the highly active Neovolcanic Zone of Iceland on the basis of TerraSAR-X, TanDEM-X, RapidEye and HRSC data. The goal is the establishment of a SAR based operational monitoring service for risk assessment, early prediction and damage mitigation. Due to 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. Within the TSX project (GEO0100) we received additional X-band data since 2009. This new generation of SAR data allows remote NRT monitoring on subglacial volcanoes (e.g. Eyjafjallajökull 2010, Grímsvötn 2011) for the first time. The observations are focusing on three test sites within Icelands Neovolcanic Zone: The plateau glacier Mýrdalsjökull with the subglacial Katla volcano, the Eyjafjallajökull volcano, the western Vatnajökull ice cap covering several fissure swarms and central volcanoes and the Hekla volcano. The 1996, 1998, 2004 and especially the 2010 and 2011 subglacial eruptions of Eyjafjallajökull and Grímsvötn with its huge glacial torrents and ash production could be investigated within previous projects. Future volcanic events (Katla, Bárdarbunga, Grímsvötn) during TerraSAR-X lifetime can be expected and new methods using TSX data for NRT monitoring of natural disasters can be developed. Special research objectives are the observation of glacier dynamics (uploading/deloading) and their effects on subglacial volcanoes (external triggering) as well as the surveillance of areas threatened by melt water drainage following subglacial outbreaks. Verification of the results by ground truth data involving the determination of surface roughness as well as volcanological, geological, geomorphological, glaciological and hydrogeological studies will be a main focus. Spaceborne optical and radar data (TSX, TDX, RapidEye) as well as high resolution HRSC airborne data are essential to build up an early warning system for risk mitigation. Funding by the “Bayerische Staatsministerium für Wirtschaft,Infrastruktur, Verkehr und Technologie” (ID: 20-8-3410.2-15-2012) for all project partners is available until 2015.
