Just a week ago, the 30 October at 11:51 (GMT), the greek island of Samos (Samos en griego) has suffered a strong earthquake of magnitude 7.0 (according to the USGS). Radar satellite images allow evaluating how much the earth's surface has moved by applying interferometry and detecting differences between 2 dates (anterior / after the event)
