Gunung Sibualbuali, rising above agricultural land on its eastern flank, is an eroded Pleistocene stratovolcano. Rhyolitic-dacitic lava domes erupted from fissure vents along the Toru-Asik fault to the south are late Pleistocene or possibly Holocene in age and are considered part of the Sibualbuali volcanic center.
