활성단층 조사에 활용되는 원격탐사 기술과 사례의 고찰 = A Review on Remote Sensing Techniques and Case Studies for Active Fault Investigation

국문 초록 (Abstract)

대부분의 대규모 지진은 기존의 활성단층이 재활하여 발생하므로, 이러한 활성단층의 위치와 특성을 파악하는 것은 지진재해 연구와 지진방재 측면에서 매우 중요하다. 최근에는 활성단층 조사에서 지표지질조사에 앞서 실시하는 선형구조 분석에 다양한 원격탐사 기술이 유용하게 활용되고 있다. 본 논문에서는 원격탐사 기술 중 이러한 활성단층 조사에 널리 활용되는 위성원격탐사, 항공원격탐사, 그리고 InSAR, LiDAR 기법의 간단한 원리와 적용사례를 소개하고자 한다. 또한, GIS를 활용하여 단층활동에 의해 형성된 경사급변점과 주향이동단층의 수평변위를 분석한 사례를 소개하고자 한다. 토의에서는 항공사진을 활용하여 DEM을 구축할 때 발생할 수 있는 문제점들과 해결방안, 항공 LiDAR 기반 DEM의 문제점을 극복하여 개발한 새로운 기법인 RRIM에 대해 논의하고자 한다. 활성단층 조사에서 어떤 원격탐사 기술이 활용되는지 이해하고 각 원격탐사 기법의 장단점과 한계점을 이해하여 상황에 따라 적절한 방법을 활용하는 것은 효율적인 활성단층조사를 위해 중요하다.

다국어 초록 (Multilingual Abstract)

Since most large earthquakes occur by reactivation of preexisting active faults, it is important to understand the locations and characteristics of active faults in terms of earthquake hazard research and earthquake disaster prevention. Recently, several remote sensing techniques are broadly used for lineament analysis performed prior to field surveys in active fault surveys. The aim of this paper is introducing simple principles and application examples of each remote sensing technique (satellite remote sensing, airborne remote sensing, InSAR, LiDAR) widely used for active fault investigation. This paper also explains the analytical methods for the slope break generated by fault activity based on GIS and the horizontal displacement of the strike-slip fault. In discussion, we would like to discuss the problems and solutions on making DEM based on aerial photography, and a new developed technique (RRIM) to overcome the problems of DEM based on aerial LiDAR. Understanding remote sensing techniques used for active fault investigation and utilizing appropriate methods depending on the situation and limitations of each remote sensing technique are important for effective active fault investigation.
