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.

The Global Volcanism Program is not aware of any Holocene eruptions from Apo. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Apo page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Cloud banks ring Apo volcano west of Davao Gulf below the center of this NASA Space Shuttle image (with north to the upper left). Apo, the highest peak in the Philippines, rises to 2954 m SW of the coastal city of Davao, which can be seen at the upper right, across the narrow strait from Samal Island. Apo has a flat-topped summit with three peaks, of which the SW peak is the highest and the northern peak the youngest. No historical eruptions are known from Apo, but fumarolic activity continues.
