Abstract
The power of SAR interferometry in earthquake monitoring has been demonstrated with the Landers earthquake, where the movement of coseismic features have been measured with a typical precision of 2 to 10 millimetre over a 35000 km 2 area surrounding the event. The basic results of this technique and its limitations will be discussed and the results obtained on various sites representing various applications will be shown. These sites include the Landers site which has been monitored from April 92 to August 93. The technique may also contribute to significant advances in flood prediction by creating elevation map of flat areas with a precision better than one meter. Our method of digital elevation model elimination greatly enhances the quality of the results. Some of the limitations of the radar data used so far are now well understood. We may therefore outline the technical features of a radar satellite devoted to Earth crustal motion survey. This satellite would bring a revolution in the monitoring and assessment of natural hazards by allowing a high rate survey of the global land cover with a precision which could ultimately be on the order of a few millimetres.
