West Sumatra Province is a mountainous district nearly 3,000 metres 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.
Towering above the eastern side (i.e. the mountain side) of Padang Pariaman are two large volcanoes; Gunung Tandikat stands at 2,347m and Gunung Singalang at 2,877m, together forming twin volcanoes. Lake Maninjau, located at the north end of Padang Pariaman, is a caldera lake measuring 20 kilometres north–south and 8 kilometres east–west which formed after a large volcanic burst 52,000 years ago. The volcanic products from this giant eruption are scattered over a wide area in the north-central area of Padang Pariaman. Today these volcanic products are seen as pyroclastic flow uplands and low relief hills.
