A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and per ...

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.

Mayon Volcano
Mayon ( bcl, Bulkan Mayon; tl, Bulkang Mayon, ), also known as Mount Mayon and Mayon Volcano ( es, Monte Mayón, Volcán Mayón), is an active stratovolcano in the province of Albay in Bicol, Philippines. A popular tourist spot, it is renown ...

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 .
There are several peaks above 1000 metres in elevation. The highest point is reported as 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
A complex volcano, also called a compound volcano or a volcanic complex, is a mixed landform consisting of related volcanic centers and their associated lava flows and pyroclastic rock. They may form due to changes in eruptive habit or in t ...
. 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.
