EARLY DETECTION OF SUBGLACIAL VOLCANIC ERUPTIONS IN ICELAND
Subglacial volcanic eruptions often provide indications of activity before the actual catastrophic event:
- Ice cauldrons, i.e. surface depressions appear on top of the ice cap due to subglacial volcanic heat
- Glacial outburst floods (Ic. Jökulhlaups), i.e. meltwater torrents occur at the glacier margin
A process chain is developed in order to automatically identify such early indications, based on high spatially and temporally resolved remote sensing imagery:
- TerraSAR-X
- TanDEM-X
- RapidEye
- LiDAR, HRSC, UltraCAM
