**Mount Labo**, is a potentially active [stratovolcano](/source/Stratovolcano) in the [provinces](/source/Provinces_of_the_Philippines) of [Camarines Norte](/source/Camarines_Norte) and [Camarines Sur](/source/Camarines_Sur) in the [Bicol Region](/source/Bicol_Region) (Region V) and [Quezon](/source/Quezon) in the [Calabarzon](/source/Calabarzon) (Region IV-A), on [Luzon](/source/Luzon) Island, in the [Philippines](/source/Philippines). It is located at the northwest end of the [Bicol Peninsula](/source/Bicol_Peninsula).

## Physical features

Labo is a forested andesitic [stratovolcano](/source/Stratovolcano), surrounded by numerous [andesitic](/source/Andesitic) to [dacitic](/source/Dacitic) satellite [lava domes](/source/Lava_dome). It has an elevation of 1,544 meters (5,066 ft) [asl](/source/Above_mean_sea_level). Base diameter of this [complex volcano](/source/Complex_volcano) is 35 kilometers (22 mi).[1][2] Labo is thermally active with both warm and [hot springs](/source/Hot_spring).

## Economic activities

Mount Labo has been the object of an extensive geothermal exploration program.[2]

## Eruptions

Mid-Pleistocene eruptions beginning about 580,000 years ago formed lava domes on the northern side of the complex. The present edifice was formed beginning about 270,000 years ago, and flank lava dome emplacement took place from about 200,000 to about 40,000 years ago.[2]

The latest activity from Mt. Labo produced pyroclastic flows from the summit cone about 27,000 years ago. There have been no eruptions since.[2]

## Geology

Rock type is predominantly [hornblende](/source/Hornblende)-[biotite](/source/Biotite) [andesite](/source/Andesite) to [dacite](/source/Dacite).[1] Tectonically, Labo is part of the Bicol Volcanic belt.

## Listings

The Smithsonian Institution's Global Volcanism Program lists Labo as [Pleistocene](/source/Pleistocene).[2] [Philippine Institute of Volcanology and Seismology](/source/Philippine_Institute_of_Volcanology_and_Seismology) (PHIVOLCS) lists Labo as *Potentially Active*.[1]
