The preliminary results of an interferometric study of Piton de la Fournaise volcano, Réunion Island, with synthetic aperture radar images acquired by the ASAR-ENVISAT satellite are presented. By combining six ASAR images acquired in ascending swath 2 and descending swath 6 and 7, three interferograms spanning the period during which the eruption occurred were formed. The interferograms exhibited clear fringes patterns centered on the Soufriere pit crater, on the external northern flank of the summit Dolomieu caldeira. The study demonstrated the total efficiency and high potential of ASAR as a successor of ERS for interferometric applications.
