The aim of this study is to analyze the effectiveness of agricultural land as a disaster refuge in an earthquake fire. Safety evacuation areas and places of temporal refuge are planned in disaster prevention planning. However, they are not always close to residents. On the other hand, there are many small open spaces closer represented by agricultural land in urbanized area. But agricultural land is decreasing by land development year after year. As a result, we showed the effectiveness of planting fire preventive trees in agricultural land or putting fire resistive buildings around agricultural land against earthquake fire, thus we showed necessity to preserve agricultural land.
