Abstract. A large part of the residential areas in Turkey are at risk from earthquakes. The main factors that threaten during an earthquake poor quality building stock and soil problems. Liquefaction, loss bearing capacity, amplification, slope failure, landslide hazards must be taken into account for close to fault zones covered with younger sediments. Analyzing these separately then combining analyses would ensure a more realistic evaluation according population density than analyzing...
