Co-seismic ground motions from earthquakes in Turkey-Syria as registered by SAR data

Hristo Nikolov, Mila Atanasova

The objective of this paper is to present the results obtained from SAR data processing used to establish the ground displacements caused by a number of earthquakes that took place on the Turkey-Syria border region. The strongest events were registered on February 6, 2023. As expected, the aftershock activity was serious and up to May 1st the number of quakes with magnitude lager than 4.5 is more 180. The main data sources used in this study are satellite-borne SAR products from the Sentinel-1 mission whose large area coverage allowed production of maps that reveal the scale of the surface disruptions. Along with the said data, other data for the epicenters and regarding the established faults in the investigated region were used, too. Due to the time interval between the data acquisitions the mentioned maps portray the cumulative effect from all mentioned events which means that it is not possible to discriminate the contribution of a single event to the calculated displacements.
