On February 6, 2023, two earthquakes with magnitudes of 7.8 and 7.5 Mw occurred in Turkey, 9 hours apart. The earthquake epicentres were in the Pazarcık and Ekinözü districts of Kahramanmaraş. These earthquakes, which were felt across a large area and caused a considerable deal of destruction and damage, impacting 11 provinces, were particularly damaging to the province of Hatay. These earthquakes led to the deaths of more than 50,000 people in Turkey and around 9,000 people in Syria, as well as more than 120,000 injuries. Following the earthquakes, more than 33,000 aftershocks with magnitudes up to 6.7 Mw were recorded. As a result of the tectonic activity on land and under the sea, the mainland shifted to the west for meters, creating large rifts in the land. In the gulf region of the Iskenderun district of Hatay, subsidence and settlements occurred on the ground and the coastline changed. Following that, sea waves and flooding occurred due to northerly wind and the tide blowing from the sea to the land nearby. Subsequently, due to the northerly wind and tide blowing from the sea to the land in the region, sea swells and sea floods occurred. This situation caused the residential areas on the coast to be flooded. Due to the rise in the sea level, vehicle traffic was affected, the streets were flooded. The basement floors of shops, workplaces, hospitals, social facilities and residences facing the streets along the coast were filled with sea water and became unusable and people suffered substantial economic losses. Downfall in the structures and cracks in the walls were observed. The reinforcements in the foundation and columns began to corrode due to the salt water. Harbour, marina, boatyards, boats etc. were severely damaged. this study reveals the structural and economic effects of sea level rise in Iskenderun.
