Near surface electrical resistivity structures around an active fault trace in Weh Island, Indonesia

Near-surface investigation has been carried out in Cot Abeuk, Weh Island, Indonesia. The area is part of the Seulimeum segment active fault, the northernmost branch of the Great Sumatran Fault. We measured two parallel electrical resistivity tomography profiles on the area with the direction perpe...
