Abstract

In this study, IGS(International GNSS Service) stations were processed by the method of PPP(Precise Point Positioning), and velocities of crustal movements about the region of the Korean Peninsula were calculated precisely. The characteristics of crustal movements around Korean Peninsula were understood by velocity calculation of crustal movements. We confirmed from the result which calculated by crustal movement velocity shows the movement Eurasia and North America plate move to south-east, and Philippine plate moves to north-west. This result is respected to be utilized as a basic data about analysis of earthquake and earth physics.

최근 한반도 주변의 지진발생이 증가하고 있는 추세이며, 이에 따라 최선의 자료에 의한 지각변동 해석이 필요한 시점이다. 본 연구에서는 IGS(International GNSS Service) 상시관측소의 GPS 자료를 이용하여 한반도 주변에서 일어나고 있는 지각변동의 절대속도를 정밀하게 산출하였으며, 지각변동 모델과의 비교 및 기간별 지각변동 분석을 통해 지각변동특성을 파악하고자 하였다. 산출된 지각변동속도로부터 유라시아 및 북아메리카 판은 남동쪽 방향, 필리핀 판은 북서쪽 방향으로 이동하고 있음을 알 수 있었다. 또한 한반도를 기준으로 한 상대속도 산출을 통해 북아메리카 판과 필리핀 판이 우리나라방향으로 이동하고 있음을 파악하였다. 이러한 연구결과는 향후 동아시아 지역의 지진 및 지구물리 연구에 널리 활용될 것으로 기대된다.
