Geological Summary

Numerous pyroclastic cones and craters dot 60-km-wide Jolo Island at the SW end of the Philippines archipelago. Jolo lies in the Sulu archipelago, about 150 km SW of the tip of the Zamboanga Peninsula on SW Mindanao Island. The isolated location of Jolo and political unrest have inhibited geological studies of the volcanic island. Youthful-looking Tumatangus volcano forms the 811 m high point of the island. Bud Dajo (or Buddajo) is a young basaltic cinder cone that reaches 620 m elevation; nearby cones are Matanding, Guimba, and Sungal. Hot springs have been reported at craters on Cagayan Sulu, and solfataras at Siit Lake. A tsunami accompanied a possible submarine eruption in 1897. A reported eruption in 1641 actually reflected ashfall from the eruption of Parker volcano on Mindanao.

Photo Gallery


The dumbbell-shaped, E-W-trending Jolo island contains numerous pyroclastic cones and craters, some of which are visible in this Space Shuttle image with north to the upper left. The island is about 60 km wide in an E-W direction; its largest city, Jolo, lies on the northern coast (left-center). The isolated location of Jolo at the SW end of the Philippines archipelago as well as political unrest have inhibited geological studies of the volcano.

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.
