Geology
editThe mountain is part of the Tawau volcanic field which contributed to the prominent topographic features of the Semporna Peninsula in northeastern Borneo and the western side of a valley in its middle section.[3][4][5] The low volcanic cone is north of Sebatik Island and has a roughly 300-m-wide crater breached to the south. Two young lava flows extend almost to the coastal plain. The flows are considered younger than a lava flow radiocarbon dated at about 27,000 years before present, and the extrusion of basaltic lavas possibly continued into the Holocene epoch.[6] Presence of geothermal activity has been reported in the surrounding mountains.[7][8]

In Sabah, Tawau's Bombalai volcano is currently a dormant volcano and, since it estimated to have erupted thousands of years ago, it can be regarded as an ancient crater. Bombalai cinder cone is only a half-an-hour jungle walk from the entrance of Tawau Hills National Park.
