Abstract
Radar images of the European environmental satellites ERS-1 and ERS-2 provide the possibility to observe the earth's surface independently from daytime or cloud cover. Radar interferometry, which compares phase information from different radar images, is an excellent technique to measure surface displacements associated with natural hazards. Interferometrically derived motion maps can form an important base for model calculations and future damage prevention. After a theoretical introduction, we present examples of interferometric motion measurements on landslides, glaciers and earthquakes. As an important application for future interferometry systems the monitoring of areas with high earthquake risk is discussed in more detail. The presented satellite data were processed at the German Remote Sensing Data Centre (DFD).
