摘要：Recently the possibility of an earthquake has become one of the most important subjects in lots of countries especially in Turkey. For that reason, the possibility of an earthquake gains ground due to its devastating physical and psychological effects. Because of these physical losses and its psychological effects, people who experience the earthquake generally become sensitive and provident. Although disaster management had been established before the earthquake, the studies after the earthquake prove the fact that decreases in the loss of lives is inadequate. In this study, the aerial photographs have used which have been obtained before and after the earthquake. An algorithm is developed that determines the damaged buildings as semi-automatic. The principle of this study is analyzing the buildings' image histograms and determining their conditions. G.lcük and Adapazar. regions before and after the earthquake have been used for the analysis of the image histograms that belong to the buildings in the aerial photographs. Our empirical results have shown that the histograms of the undamaged and damaged buildings have different forms. For this reason, utilizing the histogram analysis, the conditions of the damaged buildings have determined by using a semi-automatic process. The important pre-condition for this study is the digital maps of the study area to be in existence. Briefly, to form the histograms, the coverage areas of the buildings that are after the earthquake photographs in vector format are found and the image histograms are calculated from those areas. The purpose is to determine the damaged buildings quickly during the earthquake and contribute to the disaster management. It is thought that, through the results that are to be obtained, it will be possible to direct the rescue mission correctly, estimate the number of loss of lives and take healthy precautions
