Abstract

Both 1900 years of historic literature and recent instrumental seismic records indicate the Korean Peninsula has repeatedly experienced small and large earthquakes. This study has used historical and instrumental records of Korea to investigate the characteristics of earthquakes in the peninsula. Results of GIS spatial analyses indicate Pyongyang, the capital of North Korea, is more vulnerable to the earthquake hazard than that of other regions in the Korean Peninsula. It is also noted that Pyongyang is exposed to high risks of other natural and social disasters because of the high population density and concentrated infra structures. Scenario shake map drawn up assuming a magnitude 6.7 earthquake, which was experienced in A.D. 502 in the area, indicates that 51.1% of the city are exposed to PGA 0.24 g or higher. Recent statistics by the Statistics Korea also indicates the North Korea is far more vulnerable to disasters than those in the South Korea. Results of the preliminary study provide essential information for comprehensive understanding of earthquake hazard estimation in Korea including the North Korea.

한반도에서는 크고 작은 지진이 꾸준히 발생하고 있음을 역사문헌과 계기지진 관측 자료를 통해 알 수 있다. 본 연구에서는 역사지진과 계기지진 자료를 이용해 지리정보시스템(GIS)의 공간분석 결과, 북한의 평양지역이 지진으로부터 가장 위험한 지역으로 결정되었다. 평양은 북한의 수도로서 인구와 구조물의 밀집도가 높아 지진뿐만 아니라 재해로 인해 큰 위험에 처할 수 있다. 502년 평양에서 발생한 규모 6.7의 지진을 토대로 지진동 지도를 작성한 결과, 0.24 g보다 높은 지진동을 느낄 수 있는 지역이 평양지역의 약 51.1%를 차지한다. 또한 통계청 자료에 의하면 북한은 우리나라보다 재해로부터 열악한 환경에 처해 있음을 확인할 수 있었다. 이번 연구결과는 향후 북한을 포함한 우리나라의 포괄적인 지진재해예측 연구에 유용한 정보로 사용될 수 있다.
