Mount Bombalai ( Malay: Gunung Bombalai) is a volcanic cone mountain in the Tawau Division of Sabah, Malaysia. [1] It reaches a height of approximately 531 metres (1,742 ft). [2]
The 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.
