Ragang volcano rises to 2815 m at the NE end of a series of young volcanic cones SE of Lake Lanao in central Mindanao. A 3-km-long lava flow extends to the SE from the deep summit crater. Ragang is the most frequently active volcano on the large southern Philippines island of Mindanao and 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 and consist of moderate explosive activity from the summit crater.
