The earthquake in Turkey and Syria was powerful, and images of the damage there show just how of a severe impact was felt. But a scan from the satellite ALOS-2 from the Japan Space Agency in collaboration with NASA really shows how much land moved during the quake.
It indicates that some areas along the fault line in Turkey moved upwards of 5-6 feet of pure land movement and deformation. This is why the shaking lasted so long and was so intense for the hardest hit areas.
