 Abstract: The earthquake (Mw=7.7) on 06 February 2023 (01:17 UTC) in Kahramanmaras, Turkiye caused a tsunami in the Eastern Mediterranean despite its strike-slip characteristic and epicenter (37.1123N 37.1195E) ~90 km inland. The earthquake ruptured at a shallow depth (~5) striking about NE-SW on the East Anatolian fault zone and having a devastating impact in southeastern Türkiye. Kandilli Observatory and Earthquake Research Center (KOERI), which is one of the Tsunami Service Providers of the UNESCO IOC NEAMTWS issued four tsunami messages with a tsunami warning 15 min after the earthquake with expected tsunami amplitudes more than 0.5 m. The generated tsunami was recorded at four tide gauge stations, (Iskenderun-Arsuz, Erdemli, Gazimagusa (Famagusta), and Girne (Kerinya) in the Eastern Mediterranean. The recorded water level fluctuations were analyzed after detiding to extract the arrival time of the wave and its profile. For the assessment of the 06 February 2023 tsunami, numerical simulations were performed using the tsunami numerical model NAMI DANCE to understand the generation mechanism and possible location. It is important to identify those features for future preparedness in the area. This small-scale tsunami has been an important reminder in this regard and a test for the effective working of the early warning system. A field survey was also performed on 11-13 February 2023 to investigate the tsunami traces, conduct eyewitness interviews and coastal structure performance evaluation. The simulations are repeated using the survey findings and the modeling results are compared with the measurements. The results will be presented with discussions.
