Abstract

Rapid increase in
population results in rapid but not planned growth of residential areas and
subsequently residential areas shift from their initial position to various
risk including regions. Natural disasters are inevitable once the cities are
not properly planned in countries like Turkey characterized with geological,
geomorphological and climatological diversity. It is worthy to note that
disaster risk profile in Turkey is very high according to the natural disasters
historical data. Of the natural disasters, rock fall is one of threats for
Turkey. The definition of rock fall may be simplified as quantities of rock
falling freely from a cliff face. In order to monitor the possible and
potential rock fall risks, base maps of the study area (Kilis, Turkey) was
obtained using geographical information system (GIS) techniques and remote
sensing data. The base maps were produced considering the parameters affecting
the rock fall. Finally, rock fall risk map for the region was obtained by overlapping
the maps using GIS techniques. The results exhibit that 3.22 % of the regions
has high potential risk of rock fall. Based on the results, local decision
makers concerned with urbanization plans should consider the regions with high
rock fall risks. Otherwise, the loss of life and property is inevitable as
consequences of natural disasters
