Mount Matutum is a symmetrical stratovolcano located in southern Mindanao, NW of Sarangani Bay and 30 km NNW of General Santos City.
The mountain, a popular hiking destination, has a well-preserved summit cone and a 320 m wide and a vegetated 120 m deep summit crater. The crater is breached by 3 large canyons.
The plains around Matatum volcano are covered by silicic pyroclastic-flow deposits, the youngest of which were radiocarbon dated at about 2000 years ago. 2 thermal areas, Akmoan and Lianan, are found on the WSW flank of the volcano.
