Below is a summary of eruption dates and Volcanic Explosivity Indices (VEI).

The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.

The symmetrical Matutum stratovolcano rises to 2286 m in southern Mindanao, NW of Sarangani Bay. The summit of the andesitic-to-dacitic volcano is truncated by a well-preserved 320-m-wide crater that is breached by three gorges and has a 120-m-deep, densely forested floor. Widespread silicic pyroclastic-flow deposits surround the volcano, which overlooks the major city of General Santos. The youngest pyroclastic deposits were dated at about 2000 yrs BP. A report stated that Matutum volcano was "smoking" on March 7, 1911 (Neumann van Padang, 1953). The Akmoan and Lianan thermal areas are located on the WSW flank of the volcano.
