AbstractNatural hazard events such as earthquakes and volcanic eruptions can be successfully studied with the Synthetic Aperture Radar (S AR) that is capable of mapping sub-centimetre ground deformation over large areas using Interferometric SAR (InSAR) processing methodology. After the Japanese ALOS and European ENVISAT satellites completed their operation in 2 011 and 2 012 respectively , the only SAR sensors left in operation were the X- b and German TerraSAR-X, Italian Cosmo-SKYMED and C- band Canadian RADARSAT-2. In this poster we present a number of case studies were RADARSAT-2 has proven to be the sensor with the best archived coverage and characteristics, including excellent spatial and temporal resolution and a wavelength that is superior for land observations. Using RADARSAT-2, we successfully mapped a number of large earthquakes in Canada, Central America, Iran, Italy, and Russia, and volcanic deformation in Chile, Hawaii, Italy, and Spain. Here we will present deformation maps for some of the natural hazard events that were studied and provide suggestions for future missions.
