Abstract
We describe the remote sensing tool known as satellite radar interferometry and its application for measuring crustal deformation at volcanoes, with about 1 cm accuracy. The technique relies on synthetic aperture radar (SAR) images acquired by radar satellites at different times. These images are combined into interferograms, which reveal information about the change in range from ground to satellite, expressed as interferometric fringes. We give numerous examples of radar interferometric applications to volcanology that demonstrate that interferometry has already been used to measure volcanic deformation throughout the eruptive cycle, using all available spaceborne radar instruments. Radar interferometry is an important tool for worldwide volcano monitoring, because basic volcanic phenomena are properly observed, with some caveats, in all climate types, from tropical to sub-polar.
