This study subclassifies the causes of forest fires in Korea and relevant forest fire direction indicators with intent to ascertain the correct causes of forest fires and ultimately increase the accuracy of statistics conducive to preventing forest fires. Specifically, this paper subclassifies the seven forest fire cause indicators established in Korea into a total of 30 indicators including six types of human error. Also, it subclassifies the forest fire direction indicators, characterizing the burn patterns of forest fires, into 14 indicators, i.e. V–pattern, protection, grass stem, freezing, spalling, curling, sooting, staining, lightning, depth of char, angle of char, extinction pattern, cup–shaped and ash indicators, and defines the burn characteristics of each indicator. The findings will serve as some reference data for determining the causes and investigating the burn patterns of forest fire.
