Fault Rupture Mapping of the 6 February 2023 Kahramanmaraş, Türkiye, Earthquake Sequence from Satellite Data (ver. 1.1, February 2024)

Metadata Updated: July 20, 2024

This data release contains two datasets that depict fault rupture on the East Anatolian and Çardak faults resulting from the Mw7.8 and Mw7.5 earthquakes in Turkey (Türkiye). It contains two additional datasets that describe satellite imagery coverage and observation gaps. The 6 February 2023 earthquake sequence caused >500 km of combined surface rupture on the primarily left-lateral strike-slip East Anatolian and Çardak faults. The two datasets represent (1) simplified fault traces inferred from displacement discontinuities in interferometric synthetic aperture radar (InSAR) scenes mapped at 1:750,000 scale (“simple_faults”) and (2) detailed mapping of fault surface rupture observed on high-resolution (<1.0 m/pix) optical images from the WorldView 1, 2, and 3 (© 2023 Maxar) satellites mapped at 1:1,500 scale (“surface_rupture_lines”). The mapping is based on satellite data and has been ground checked in select locations. These datasets were mapped primarily from February 6 to 17, 2023, with minor updates and quality control thereafter. They have undergone full peer review but remain subject to revision as more information becomes available. Datasets are provided in shapefile, KML, and geoJSON formats. Updates to version 1.1: A minor update, version 1.1 contains new “simple_fault” and “surface_rupture lines” files. The “simple_fault” linework has been updated to include the correct orientation of the northern Narlı fault, checked on WorldView images and on the ground. The “surface_rupture_lines” linework has been updated with minor additional fault traces that were overlooked in v1.0 and updated locations of some surface rupture lines to agree with on-the-ground reconnaissance.
