Geological Summary

Located at the NE tip of Mindanao, Paco (also known as Manlayao) is truncated by two nested calderas, 2.5 and 5 km in diameter. The basaltic-dacitic volcano is located east of the N-S-trending Philippine Fault that cuts across eastern Mindanao. Andesitic lava domes rim a breached crater, and the youngest dated rock is an overlying basaltic lava flow dated at about 90,000 yrs +/- 40,000 yrs BP. Legends record a major caldera collapse eruption (Wolfe 1982, pers. comm.). The age of the last eruption is not known, although the volcano currently displays fumarolic activity.

The Global Volcanism Program is not aware of any Holocene eruptions from Paco. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Paco 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.

Paco volcano (also known as Manlayao) occupies the large peninsula forming the NE tip of Mindanao, north of Lake Mainit (bottom). The volcano is truncated by two nested calderas, 2.5 and 5 km in diameter and is located east of the N-S-trending Philippine Fault that cuts across eastern Mindanao and defines the western shoreline of the peninsula in this Landsat image. Legends record a major caldera collapse eruption, although the age of the last eruption is not known.

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.
