Abstract
On February 6th, 2023 at 01:17:35 UTC a Mw 7.8 earthquake occurred about 15 km southeast of the mapped trace of the East Anatolian Fault Zone (EAFZ). About 9 hours later, at 10:24:49 UTC, a Mw 7.6 earthquake occurred along a separate structure to the north. Such two earthquakes can be considered the largest in the EAFZ system in instrumental times and produced the largest surface ground motions and widespread liquefaction phenomena. The coseismic displacement field due to this pair of mainshocks cover up more than to 400x400 km. In order to investigate the surface effects, the GEOSAR Lab. has acquired and processed a set of Sentinel-1 data covering the overall affected region, to analyze ground deformation patterns, while CosmoSkyMed data have been focused on the detection of damage in the urban areas within, by exploiting SAR intensity signals. The latter allowed to obtain damage proxy map on Kahramanmaras and Gaziantep cities, and on some other villages in the large epicentral region.
