Paco volcano (also known as Manlayao or Paco-Manlayao) is located at the NE tip of Mindanao Island, Philippines.
It is an basaltic-dacitic stratovolcano complex truncated by 2 nested calderas, 2.5 and 5 km in diameter. The volcano is located east of the N-S-trending Philippine Fault which cuts through eastern Mindanao.
It has a breached crater with andesitic lava domes. The youngest dated rocks are from a basaltic lava flow between 90,000 and 10,000 years old. Local legends tell about a major caldera collapse eruption.
The age of the last activity is not known, although the volcano currently displays fumarolic activity.
