Field Observations of Surface Rupture and Fault Displacement in the 2023 M7.8 Pazarcık, Türkiye Earthquake

Field observations of surface rupture extent and fault displacement are critical to improving our understanding of rupture processes in the 6 February 2023 earthquakes in the Kahramanmaraş region of Türkiye. This data release includes two primary datasets depicting the 2023 M7.8 Pazarcık, Türkiye earthquake rupture: 1) surface rupture mapping (lines) and 2) measurements of left-lateral and vertical fault displacement (points). These observations were made in the field, northwest of Pazarcık, Türkiye along the East Anatolian (EAF) and Narlı faults between 2 and 11 June 2023. Surface-rupture mapping consists of field observations along a 28-km-long reach of the central EAF and northern 5 km of the Narlı fault that lacked previous remote observations. An additional dataset includes observations of no surface rupture. Displacement data include 68 field observations of left-laterally and vertically displaced natural or cultural features, with 62 measurements along the central EAF and 6 measurements on the Narlı fault. Collectively, these data support scientific and humanitarian response efforts, provide field observations for comparison to remote data, and help improve our understanding of the geologic context of the 2023 Kahramanmaraş region earthquakes.
