DIFFERENTIAL INTERFEROGRAM OF THE BAM (IRAN) EARTHQUAKE (Ms=6.5) IN DEC. 26, 2003

Three ENVISAT ASAR images were used dated Dec. 3, 2003, Jan. 7, 2004 and Feb. 11, 2004 (data source: European Space Agency). The Atlantis EVInSAR v.3.1 s/w was used following the three-pass interferometric method. The first two images (Bp=570m) were used to create the DEM (step 1), and the first and third image (Bp=0.6m) to create the differential interferogram, using the generated DEM as an input external DEM.
