Abstract: The infrastructure in Korea was built after the significant growth in the economy after 1960. Today, this aged infrastructure has been inappropriately maintained and managed without awareness of man-made disasters. Even though the Korean government established complementary laws and regulations to prevent man-made disasters, these disasters have occurred in various locations and have been presented as social problems, they have also resulted in large social and economic losses. This paper examines both historical reviews and damage assessments and provides improvement to plans for typical man-made disasters including fire, collapse, explosion, traffic accidents, and environmental pollution.
