Abstract

Since the detection of surface deformation at Mt. Etna it was believed that space-borne radar interferometry may provide a tool to monitor most of the Earth's active volcanoes. We have studied a large number of volcanoes from different environments and show that ERS C-band radar interferometry can be used only to observe certain volcanoes with particular conditions. The best targets for ERS C-band interferometry are shield volcanoes and large calderas. Stratovolcanoes are less suited for radar interferometric observations due to geometric distortions and severe environmental conditions. Interferometric coherence is often lost because of snow coverage and ash deposits.
