Many people have no idea that Malaysia is also has volcanic montains or actually a volcanic mountain. Located at the Borneo Island specifically in the east coast of Sabah, Tawau you can find the Bombalai Volcano.
Bombalai Volcano is actually an extinct volcano in Tawau, Sabah. the only volcanic mountain in Malaysia. Unlike some countries like Indonesia with many active volcanic mountains.
I doubt the majority of people in Tawau really knows what Bombalai Hill is. In all the years I have been there, no one has ever mentioned volcano. I have always wondered about Bombalai Hill in Tawau. It is one of the the only predominate hills you can see close to Tawau town. Imagine my surprise to read that it is an extinct volcano in Sabah which was last thought to have erupted some 27,000 years ago.
Bombalai hill is some 530 meters high and marks the only known Holocene volcano eruption in Borneo.
So.. Is Bombalai Volcano Dormant Or Extinct?
The possibility of Bombalai erupting again is unlikely to happen any time in the near future. It is situated too close to populated areas. It’s never been heard that Bombalai being a volcano, nor an folk-lore about a volcano in Sabah.
No one knows when the last eruption was and is listed as unknown. Carbon dating tells us that the lava rocks were formed possibly some 27,000 years ago.
Country: Malaysia
Subregion Name: Borneo
Volcano Number: 0610-01-
Volcano Type: Pyroclastic cone
Volcano Status: Holocene?
Last Known Eruption: Unknown
Summit Elevation: 531 m 1,742 feet
Latitude: 4.40°N 4°24’0″N
Longitude: 117.88°E 117°53’0″E
Mount Bombalai is part of a volcanic field on the Semporna Peninsula in the NE part of the island of Borneo. The volcano is part of the Malaysian province of Sabah, across Cowie Harbor from the the Indonesian province of Kalimantan. The low volcanic cone is located 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 were considered younger than a lava flow radiocarbon dated at about 27,000 years before present, and the extrusion of basaltic lavas possibly continued into Recent (Holocene) time (Kirk, 1968). This marks the only known area of possible Holocene volcanism on Borneo. Other areas of late Quaternary dacitic and basaltic volcanism occur along the Semporna Peninsula.
