Abstract

Subduction has been the focal point of numerical studies for decades because it plays an important role in the Earth's mass and energy circulations and generates earthquakes and arc volcanoes which are closely related to the human lives. Among the studies on subduction, numerical modeling has been broadly applied to the quantitative studies on the subducting slab in the mantle which cannot be directly observed. In this study, we benchmark the numerical subduction modeling using a finite element package, COMSOL $Multiphysics^{(R)}$ and the results are consistent with the previously reported benchmark results.

섭입은 지구의 물질 및 에너지 순환에서 중요한 역할을 담당할 뿐만 아니라 우리의 삶에 밀접한 지질 현상인 지진과 호화산을 발생시키므로 많은 연구가 이루어져 왔다. 그 중에서 맨틀 내부의 섭입해양판처럼 우리가 직접 관찰할 수 없는 곳에서 발생하는 지질 현상에 대한 정량적 연구에 컴퓨터 수치모델링이 널리 이용되어 왔다. 이 연구에서는 다양한 연구진들에 의해 사용되고 있는 섭입대 수치모델링의 벤치마크를 수행하였다. 섭입대 수치모델링을 위하여 유한요소법 기반 상용 소프트웨어인 콤솔 멀티피직스를 사용하였으며 계산된 결과는 과거 수행된 벤치마크 결과와 잘 일치하였다.
