Rapid Characterization of the February 2023 Kahramanmaraş, Türkiye, Earthquake Sequence

Abstract The 6 February 2023 Mw 7.8 Pazarcık and subsequent 7.5 Elbistan earthquakes generated strong ground shaking that resulted in catastrophic human economic loss across south-central Türkiye northwest Syria. rapid characterization of the earthquakes, including their location, size, fault geometries, slip kinematics, is critical to estimate impact significant seismic events. U.S. Geological Survey National Earthquake Information Center (NEIC) provides real-time monitoring globally, source estimates. Here, we describe products made available by NEIC over two weeks following start earthquake sequence southeast Türkiye, evolution, how they inform our understanding regional seismotectonics hazards. kinematics rupture for was complex, involving multiple segments. Therefore, incorporating observations from mapping characterizing these Dense local datasets facilitated robust assessment once were obtained converted product input formats. We discuss may improve timeliness future hazards, particularly case complex ruptures.
