In this study, the building-ground relationship in the areas affected by the February 6 Kahramanmaras earthquakes was determined, and the risk of building collapse in future earthquakes was analyzed. Remote sensing techniques determined the collapsed building-soil relationship, and the frequency ratio method was applied by utilizing Geographic Information Systems techniques to assess the risk of collapse in earthquakes. According to the research results, 84% of the collapses occurred in flat areas. On the other hand, 49.7% of the collapses occurred in the 0-500 m elevation range. In particular, it was determined that 46% (110.8 km(2)) of the collapsed buildings occurred on alluvial land belonging to the Quaternary period. According to the earthquake frequency analysis of the total 108,812 km(2) area considered in this study, 43.72% of the area is at the Risky level, indicating that a large part of the region is at significant earthquake risk. Moreover, Hatay, Adana, Osmaniye, Sanliurfa, Kahramanmaras, and Malatya are the provinces where the risk of collapse of buildings in an earthquake is high. These results reveal the necessity of analyzing by considering many criteria in determining residential areas in provinces at risk of earthquakes.

Döner, Fatih; Kaya, Erhan
While preparing PTL (Power Transmission Line) projects, the land where the PTL is crossing is determined by considering criteria such as economy, environment and security. The realization of PTL projects is possible after acquisition of property of these lands. In this study, the process of acquisition land property in the implementation of PTL projects is evaluated. When data are examined, it is seen that the number of lawsuits filed against the PTL in past year was 15759 and rate of non-court settlement with land owners in the five-year period was 13%. The main factor for the high number of lawsuits and low settlement rate is real estate valuation studies in determining the price to be paid for land to which the PTL will be established. As land value determined as a result of valuation methods, criteria and rates referenced does not reflect real value in most cases, no agreement can be reached with the land owners. It is considered that most ideal solution from a legal point of view is to prepare a holistic valuation law that regulates real estate valuation activities, from an organizational point of view is to set a connection between cadastre and real estate valuation and from a technical point of view is to set-up a database which enables managing properties of real estates and their up-to-date values.
