Mount Ragang

Mount Ragang, also called Mount Piapayungan and Blue Mountain by the local people, is a stratovolcano on Mindanao island in the Philippines. It is the seventh highest mountain in the Philippines.
Mount Ragang

Subregion Name:Philippines - Mindanao
Volcano Number:0701-06=
Volcano Type:Stratovolcano
Volcano Status:Historical
Last Known Eruption:1873 
Summit Elevation:2815 m9,235 feet

Longitude:124.50°E124°30'0"E

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.

Ragang volcano (above and to the right of the center of this Space Shuttle image) rises to 2815 m in central Mindanao. Illana Bay lies to the SW at the lower left, and most of Lake Lanao can be seen at the upper left. Ragang is the most frequently active volcano on the large southern Philippines island of Mindanao. Historical eruptions, many of which were at one time attributed to neighboring Makaturing volcano, have been recorded since 1765. Makaturing and Latukan volcanoes are also visible to the SW of Ragang on this image.

Physical features

Ragang has an elevation of 2,815 metres (9,236 ft) and a base diameter of 32 km (20 mi).
It is the most active volcano on Mindanao, and is part of a string of volcanoes in what volcanologists call the Central Mindanao Arc.

Eruptions

There is still some confusion on the number of times Ragang erupted. The Philippine Institute of Volcanology and Seismology lists eight eruptions with the last one occurring in July 1916. But the Smithsonian Institution's Global Volcanology Programs, citing the Catalog of Active Volcanoes of the World (Neumann van Padang, 1953), suggests that some eruptions attributed to nearby Makaturing were actually those of Ragang.
Ragang is one of the active volcanos in the Philippines, which are all part of the Pacific ring of fire.
