“…The Elmalı Formation, where landslides were predominantly observed, consists of grey, greenish grey, dark grey, light brown, coarse-fine-grained, thin-thick bedded, basal-structured sandstones, and darker coloured siltstones and clay stones. Small amounts of debris flow and conglomerate levels were also determined (Orak, 2017). Fine-grained parts showed a deformed-sheared and highly chaotic appearance (Orak, 2017).…”

“…SW Türkiye is under the threat of mass movements due to its old (thrust tectonics-nap tectonics) and current (seismicity due to active faults) tectonic structure, highly variable-sharp morphological structure, and high precipitation rate (Cengiz & Ercanoglu, 2022;Duman et al, 2009Duman et al, , 2011Orak, 2017;Orak et al, 2019;Şenel, 1997a;Tosun et al, 2021;Türe et al, 2021). The relevant ministry declared this area a disaster region in 1964 because some of the large-scale movements covered by this study had a devastating effect on human life (Orak et al, 2019). After that, it was reported that landslides significantly impacted life in the winters of 1978-1979, and the Seydikemer-Antalya highway was closed to transportation and reduced to a single lane (Bozyigit, 2020).…”

“…The Elmalı Formation, which is made up of Upper Eocene and Lower Miocene deformed clastic deposits, is a formation with mass movement, as highlighted by Orak (2017) and Orak et al (2019).…”

“…There is no information on the amount of deformation in the larger region, which has also been documented in other studies (Cengiz & Ercanoglu, 2022;Duman et al, 2009Duman et al, , 2011. Moreover, variations in the region's susceptibility maps can be seen based on observation and a variety of analytical techniques (Cengiz & Ercanoglu, 2022;Duman et al, 2009Duman et al, , 2011Orak, 2017). Since InSAR analysis enables tracking of deformation over wide areas, it is believed to provide particularly important data for evaluating landslides in this region.…”

“…For this purpose, the validity of the current InSAR results was also assessed together with an analysis of the landslide inventory data. Furthermore, as claimed by Orak et al (2019), it has been attempted to visually depict large-scale earth flow-earth slide mobility.…”

This study uses multitemporal InSAR images to assess different types of mass movements occurring in the Seydikemer (Muğla, SW Türkiye) district. A major highway connecting the Fethiye district and Antalya province and numerous small settlements of various sizes are found in the study area. In terms of summer tourism, they are Türkiye's most well‐known locations. Since the 1960s, at least according to official records, mass movements in this area have been known to negatively impact human life. Some areas have even been declared disaster zones for this reason. However, the movement's size, type, and susceptibility to landslides have all been studied in the last 10–15 years. With satellite images and field studies, distinctive lobate‐shaped movements were classified as inactive and active. During fieldwork, characteristic features such as rough topography and bending trees were easily observed and indicated extremely slow and large‐scale movement. In this study, it was found that movement less than 7–8 mm/year could be classified as ‘extremely slow’ mass movement like a ‘creep’, and moving up to 43 mm/year was evaluated as ‘very slow’ movement and ‘earth slide’ on a rigid surface. The examined moving masses with lobate geometry are activated by natural factors such as valley slope direction, stream bed flow direction, erosion of the toe of the river valleys, earthquakes, excessive precipitation, or human activities such as road opening.
