전 세계적으로 다양한 연구기관에서 구마모토 지진에 대해 연구한 결과는 무엇인가요? | , 2017).그 결과 지진에 영향을 미친 단층은 북동 방향으로 뻗어진 후타가와 단층(Futagawa Fault)과 히나구 단층(Hinagu Fault)이라는 사실과 이 지진이 정단층과 우수향 주향이동 단층에 의하여 발생한 것 역시 알려졌다(Baek et al., 2018a; Himematsu and Furuya, 2016; GSI, 2016a). 또한 이어서 지속적인 여진으로 인하여 상당한 추가 지표변위가 발생한 사실도 발표되었다(GSI, 2016a). | |
위성레이더 간섭기법이란? | 위성레이더 간섭기법(SAR interferometry)은 서로 다른 시기에 획득한 위성 레이더 영상에 대하여 상대적인위상차를 계산함으로써 발생한 관측방향(Line-of-Sight)지표변위를관측할수있다. 이기술은위성의촬영범위내수십~수백킬로미터의영역에대하여 1차원지표변위를 획득하는 데에 널리 활용되고 있다(Jo et al. | |
남북방향의 지표변위를 관측하는 데 오프셋 트래킹 기법을 활용하는 이유는 무엇인가? | , 2015). 오프셋 트래킹 기법은 강도교차상관기법(intensity cross-correlation)에 의하여 변위를 위성의 관측방향과 비행방향에 대하여 모두 측정하기 때문에 남북방향의 지표변위를 관측하는 데에 활용할 수 있다(Chae et al., 2017; Baek et al. |
