İBB analyzed the district by district by conducting the field study of the landslide risk carried by Istanbul. The study was shared with the public through the Istanbul Province Landslide Information Inventory Project. In the project, which is of great importance in terms of durable spatial planning and urbanization-oriented disaster action plans in Istanbul, 63 landslide areas, 267 of which are located on the Canal Istanbul route, were identified.
Istanbul Metropolitan Municipality (IMM) continues its efforts to keep the earthquake and related risks on the agenda of the city. In line with the Earthquake Mobilization Action Plan, IMM, which started to work on 'Building Detection Scans', also examines the landslides triggered by different causes in all its dimensions. IMM conducted field studies in 39 districts in Istanbul, the city where the most deadly landslide was experienced in terms of the number of incidents, in order to have the city resilient structures. The findings were explained with the “Istanbul Province Landslide Information Inventory Project” to create awareness about landslide existence and the roads to be followed.
1.094 SCULPTURE AREA DETERMINED IN ISTANBUL
Istanbul is located at a point where natural events that can turn into disasters in terms of the earthquake danger and the risks it brings with it are experienced. In addition, mass movements such as landslides that can act with earthquakes or can pose a risk to the city without an earthquake can also cause losses. This negativity of Istanbul was also revealed in the "Istanbul Province, Landslide Information Inventory Project". In the study, where 724 kilometers of field surveys were added to 2020 square kilometers conducted in previous years, as of the end of February 4.621, local data such as geophysics and geodesy were evaluated. In the report, in which 1.094 landslide areas were detected within the borders of Istanbul, 357 of these landslide areas were (active ) landslides were seen in the class.
LANDSCAPE DANGER IN CHANNEL ISTANBUL ROUTE
An important finding in the regions in the impact area of the Kanal Istanbul route was reflected in the study. In the analyzes covering the districts where the project took place, many areas with landslide risk were determined. 267 landslide areas were detected in Avcılar, Küçükçekmece, Başakşehir and Arnavutköy districts located on the route of the project. It was determined that the majority of the mentioned landslides developed on the slopes of the channel route, and 63 of them were effective landslides..
In the study, the ranking of Istanbul province area in terms of the number of landslides was also created. In ranking; Silivri was in the top three with 120 areas, Büyükçekmece with 116 areas and Beykoz with 104 areas. When these landslides are examined in terms of effective landslides; It was observed that there are 74 areas in Şile, 61 areas in Silivri and 49 areas in Beykoz.
