摘要：

The gravity method involves measuring the earth's gravitational field at specific location and time on the earth's surface to determine the location of subsurface variations in density. It has found many applications in engineering and environmental including identifying fault. The aim of this study is to identify the location of the Seulimeum fault system in Krueng Raya, Aceh Besar (Indonesia) by utilizing gravity method. CG5 Autograv Scintrex was used to conduct the gravity method in the study area. The gravity data was taken randomly with a distance stations between 200 m to 300 m. The data was then processed using Microsoft Excel and Surfer8 software. The results was displayed in a contouring map form and from the map, the fault can be identify from the contrast of the bouguer anomaly. Local gravity value was -21 mGal to -30 mGal. At the northeast of the contour map, the value of gravity data is high compared to the value at the southwest which is low, the fault system was between these high and low value of gravity data. © 2015 ejge.
