An interferogram, calculated using Sentinel-1 acquisitions. Click for info.
An interferogram, calculated using Sentinel-1 acquisitions on 28 January and 9 February, reveals a large-scale deformation between Maras and Antakya with high gradient fringes and low coherence along the Karasu valley. According to Ziyadin Çakır, from the Department of Geology at Istanbul Technical University, the Sentinel-1 interferogram indicates that it is the East Anatolian Fault that ruptured during the first earthquake. A preliminary analysis also shows up to several metres of fault slip at Earth’s surface. Image courtesy of ESA.
