 West Sumatra Province is a mountainous district nearly 3,000 meters in elevation made of Paleozoic sedimentary rock and Igneous rock that extends from the active row of volcanoes to the east.The Great Sumatran Fault divides the center of the province—the fault topography clearly visible—in a North-northwest to South-southeast direction.The stretch of land between the central mountain range and the shore is made of volcanic uplands and pyroclastic flow uplands with a narrow coastal plain distributed along the seacoast.
