전문가설문 및 엔트로피 가중치 기법을 이용한 국내 지진위험성 평가에 관한 연구

초록

This study evaluated the national earthquake risk using expert questionnaire and entropy weighting technique. As for the indicators used in the study, 10 sub-indices were selected according to the 3 indicators of risk, exposure, and vulnerability among the 4 top indicators classified by the Intergovernmental Panel on Climate Change and used in the expert survey. Then, the risk score was calculated using the entropy weighting technique for the survey results, and the risk, exposure, and vulnerability were simply summed up, and the risk was graded into 5 levels according to a certain ratio. As a result, Gyeongju and Pohang, where large-scale earthquakes occurred recently, were ranked as the 5th grade in the southeastern region where earthquakes were most dangerous in Korea. In addition, since nuclear power plants and large-scale industrial complexes are concentrated near the southeastern region, the possibility of secondary and tertiary chain disasters is high. Therefore, it is urgently required to prepare structural and non-structural countermeasures to strengthen the earthquake disaster response capacity in the southeast region.
