In south-central Turkey on February 6, 2023 at 04:17 and 13:24 (local time), M 7.8 and M 7.5 earthquake occurred and named as Kahramanmaras (or Maras Earthquake Sequence. The M 7.8 mainshock ruptured the East Anatolian fault from Antakya to south of Malatya for about 300 km and the M 7.5 earthquake ruptured Surgu-Cardak and near-by faults north of Kahramanmaras for about 100 km. The largest earthquakes ever observed in Turkey generated very strong ground motion to severely damage extensive areas along the East Anatolian fault including northern Syria. The fatalities of more than 50000 as of the end of February exceed those of all modern earthquakes in Turkey. This session aims to exchange and share knowledge and information on the earthquake mechanisms, ground motion, surface ruptures, building damages, and secondary hazards gathered before and after the earthquakes to promote further research. Reports from broader range of survey and research on earthquakes and damages shall be appreciated.
