There are no Holocene eruptions known for Apo. If this volcano has had large eruptions prior to 10,000 years ago, information might be found in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
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. Additional discussion of data sources can be found under Volcano Data Criteria.

Apo volcano is the highest peak in the Philippines, but its geologic history is poorly known. Apo, which means master, or grandfather, rises to 2938 m SW of the coastal city of Davao and has a flat-topped summit with three peaks. The SW peak of the andesitic-to-dacitic volcano, also known as Davao volcano, is the highest and contains a 500-m-wide crater containing a small lake. The youngest crater is on the northern peak. A line of solfataras rises from a fissure on the SE side that extends from 2400 m to the summit. Apo is one of several volcanoes to which the major 1641 eruption from Parker volcano was incorrectly attributed to, but no historical eruptions are known from Apo.
