Abstract

The probabilistic seismic risk in Seoul Metropolitan Area $(atitude도 37.0^{circ}~37.8^{circ} N, longitude 126.5^{circ}~127.5^{circ} E)$ based on all Korean earthquake data of MM Intensity equal to or greater than V is evaluated by point source method. The seismic risk estimated from all data turned out to be lower than that from the data since the Choseon Dynasty during which seismic data appear to be rather complete. The damaging earthquake of peak horizontal ground acceleration greater than 0.1g turns out to occur with 90% probability of being exceeded in 200 years and 500 years when the data since Choseon Dynasty and all data are used, respectively.

MM진도(Modified Mercalli Intensity) V이상의 한반도 지진자료에 의거하여 서울 수도권일원 $(위도 37.0^{circ}~37.8^{circ} N, 경도 126.5^{circ}~127.5^{circ} E)$ 의 확률론적인 지진위험도가 점지진원방법에 의해 추정되었다. 전지진자료를 이용하여 추정된 지진위험도는 비교적 완전하다고 여겨지는 조선시대이후의 지진자료를 이용하여 추정된 지진위험도보다 더 낮다고 추정되었다. 수평지반가속도 0.1g 이상의 파괴적인 지진은 90% 초과확률로서 전지진자료와 조선시대이후의 지진자료가 이용되었을 때 각각 500년과 200년 기간에 발생한다.
