The study explores the use of magnetic method as an alternative measurement device for Seulimeum fault detection and location in Krueng Raya, Ie Seu Um, Iejue, Lamtamot (Aceh Besar) and Tangse, Pidie (Indonesia). The magnetic survey was performed using G-856 proton magnetometer and the spacing between stations was depends on the study location; Krueng Raya (50-300 m spacing randomly), Ie Seu Um (10-30 m randomly), Iejue (50 m), Lamtamot (50-70 m) and Tangse (50-200 m). The magnetic data was processed by utilising Microsoft excels and Surfer 10 software which was displayed in a form of contouring and revealed fault zones. The local magnetic value in Krueng Raya was -700 to 650 nT, Ie Seu Um was -500 to 300 nT, Iejue was -150 to 600 nT, Lamtamot was -200 nT to 200 nT and Tangse was -750 to 350 nT. The magnetic results showed the trend pattern of low and high residual value surround the study area. The highly contrast of magnetic contouring map was interpreted as fault zones. All results show that the trend pattern of fault mapped by magnetic method was trending from northwest to southeast direction. The magnetic residual map was correlated with geological map which show the existence of Seulimeum fault and proved that the study area is bounded by small faults.
