On November 12th, 2017 a magnitude 7.3 earthquake struck near the Iran and Iraq border. Just 5 days later, the Sentinel-1B satellite imaged the area effected. Using this data in combination with similar data taken on November 11th by its sister satellite Sentinel-1A, this interferogram was created by the Alaska Satellite Facility.  the colorized image shows the crustal change resulting from the quake, with the epicenter at middle of the concentric deformation rings.
