Abstract. Earthquakes are among the most devastating natural events. Interferometric Synthetic Aperture Radar (InSAR) methods are used to obtain fault parameters from co-seismic earthquakes, particularly those covering large areas. This study presents initial analyses to see the effects of the 2023 Kahramanmaraş earthquake that occurred along the East Anatolian Fault Zone of Türkiye. The study area covers the Hatay region. The analysis of different structures and earthquake-triggered landslides was conducted to investigate their impact. The small baseline method was applied to Sentinel-1 data taken in both the ascending and descending directions. The images cover the years 2019 and 2024, including the earthquake. The results vary between -20 cm/year and 25 cm/year. The earthquake co-seismic effect is visible in the time series obtained in both directions, and structural movement was observed leading up to and following the earthquake. This allows structures caused by an earthquake to be monitored afterward. Furthermore, events such as landslides and landslides that may be triggered by an earthquake can be monitored.
