2005년 Fukuoka 지진기록을 이용한 국내 및 일본의 지진동 감쇄 특성 평가 = Study on the Earthquake Ground Motion Attenuation Characteristics in Korea and Japan using 2005 Fukuoka Earthquake Records

국문 초록 (Abstract)

2005년 3월 20일 발생한 Fukuoka 지진 시 국내 및 일본에서 관측된 자료를 이용하여 지반운동 감쇄특성을 분석하였다. 또한 최근 국내 및 일본에서 제시된 지반운동 거리감쇄식을 이용한 예측값과의 비교를 통하여 국내 강지진동 예측 시 일본에서 개발된 감쇄식의 적용가능성을 평가하였다. 그 결과 동일 거리에 위치한 국내 및 일본 관측소에서 측정한 기록이 비교적 유사하게 나타났으며 국내 및 일본에서 제시된 지반운동 거리감쇄식의 예측값이 매우 유사하게 나타나 국내에서의 강지진동 예측 시 일본에서 제시된 지반운동 감쇄식을 200km 이상의 비교적 원거리에 대한 국내 감쇄식의 평가 등에 유용하게 활용할 수 있는 것으로 나타났다.

다국어 초록 (Multilingual Abstract)

The characteristics of the ground motion attenuation in Korea and Japan were estimated using the earthquake ground motions recorded at the equal distance observation stations by KMA, K-NET and KiK-net of Korea and Japan. The ground motion attenuation equations proposed for Korea and Japan were evaluated by comparing the predicted value fer the Fukuoka earthquake with the observed records. The predicted value from the attenuation equations shows good agreement with the observed records and each other. It can be concluded from this study that the ground motion attenuation equations developed for Japan can be used usefully for the prediction of a ground motion from far field earthquake more than 200 km and for the evaluation of the far field ground motion attenuation equations proposed fer Korea.
