Abstract

Located at the NE tip of Mindanao, the Paco-Maniayao volcanic complex is truncated by two nested calderas, 2.5 and 5 km in diameter. The basaltic-dacitic volcano is located east of the N-S-trending Philippine Fault that cuts across eastern Mindanao. Andesitic lava domes rim a breached crater, and the youngest dated rock is an overlying basaltic lava flow dated at about 90,000 yrs +/- 40,000 years BP. Legends record a major caldera collapse eruption (Wolfe 1982, pers. comm.). The age of the last eruption is not known, although the volcano currently displays fumarolic activity. Geological mapping by Omac and Fermin (2012; see Africa et al., 2015) indicated that the youngest volcanics were late Pleistocene.
