地質学的概要

The large Ragang stratovolcano, also called Piapayungan, is SE of Lake Lanao in central Mindanao. A crater about 5 km from the summit on the SW flank towards Latukan volcano is surrounded by mostly unvegetated volcanic material, including a lava flow extending 4 km S; this is likely from the 1916 eruption described by Maso (1917). Ragang is one of several dominantly basaltic volcanoes west of the cordillera in central Mindanao. Historical eruptions, many of which were at one time attributed to neighboring Makaturing volcano, have been recorded since 1765.
