Pocdol Mountains

The Pocdol Mountains, also known as Mount Pocdol, the Pocdol Hills, or the Bacon-Manito Volcanic Group, are a volcanic group of stratovolcanoes in the Philippines, straddling the boundary between the provinces of Albay and Sorsogon.

Location
The Pocdol Mountains form part of the boundary between the provinces of Albay and Sorsogon, in Region V, on the island of Luzon, in the Philippines.

The group is located south-east of Mayon Volcano, between Albay Gulf and Sorsogon Bay, at latitude 13.05°N (13°3'0"N), longitude 123.958°E (123°57'30"E).

Physical features
The Pocdol Mountains have a triangular footprint of about 225 km2.

There are several peaks above 1000 metres in elevation. The highest point is reported as 1102 m above sea level.

A fumarole field that contains solfataras and chloride hot springs, is reported to be located near the summit of the volcanic group.

The group is described by the Smithsonian Institution's Global Volcanism Program as fumarolic.



Eruptions
There are no reports of eruptions.

Geology
Several Pleistocene K-Ar dates have been obtained from the volcanic complex. Most igneous rocks in the Pocdol Mountains consist of pyroxene andesites with minor amounts of dacite and basalts. The area is traversed by the San Vicente-Linao Fault, a splay of the Philippine Fault.

Volcanic cones in the western part of the complex are dissected, but those in the eastern part are morphologically youthful.

The volcanic area is the host of various geothermal systems collectively called the Bacon-Manito geothermal field.
