Geological Summary

Mount Labo is a compound volcano at the NW end of the Bicol Peninsula in SE Luzon, SW of the city of Daet. The forested 1544-m-high andesitic stratovolcano is surrounded by numerous andesitic-to-dacitic satellitic lava domes. 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. The latest activity from Mt. Labo produced pyroclastic flows from the summit cone about 27,000 years ago. Thermal activity in the form of hot and warm springs continues, and Mount Labo has been the object of an extensive geothermal exploration program.

The Global Volcanism Program is not aware of any Holocene eruptions from Labo. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Labo page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Forested Labo volcano lies between the Ragay Gulf (lower left) and Pacific Ocean (top) at the NW end of the Bicol Peninsula in SE Luzon. The forested 1544-m-high andesitic stratovolcano is surrounded by numerous andesitic-to-dacitic satellitic lava domes. Eruptive activity ceased during the Pleistocene, but thermal activity in the form of hot and warm springs continues, and Mount Labo has been the object of an extensive geothermal exploration program.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
