Abstract

Applying SAR-Interferometry in remote areas, like Antarctica, has shown the high potentials for monitoring of surface changes. By using data from ascending and descending orbits, an accurate velocity fields of the ice shelf could be estimated and the separation of topography and surface changes was also demonstrated. These methods will be applied to the natural phenomena of an active volcano in Iceland to demonstrate the general use of SAR-Interferometry. With the available data sets from the ERS tandem phase, the topography and the surface changes due to the eruption of the Vatnajökull volcano in Iceland are estimated.
