초록

2012년부터 2014년까지 한반도 및 그 주변에서 일어난 지진과 지자기장 변동성과의 상관관계를 연구하였다. 웨이블릿 기반의 셈블런스 분석기술을 지진과 관련된 지자기장 변동성 분석에 사용하였다. 총자기장을 이용한 분석 결과 관측소 반경 100 km 이내에서 발생한 지진의 경우 일관적인 셈블런스 변동양상이 나타남을 확인하였고, Z축 성분 지자기장 자료를 이용한 웨이블릿 기반의 셈블런스 분석에서도 비슷한 변동양상을 확인하였다. 자료 질이 좋은 청양 관측소 지자기장 자료를 중심적으로 분석하였고, 추가적으로 보현산 관측소의 Z축 성분 자료를 해석하여 상관성에 대한 신뢰도를 확인하고자 하였다.
