Geological Summary

The Bufumbira volcanic field in SW Uganda consists of a group of about 40 cinder cones lying north of the large stratovolcanoes of the NE part of the Virunga Mountains. The cinder cones occur in clusters and were erupted along lineaments. They are typically breached on one side by lava flows. Their age is not known precisely, but they are considered younger than the stratovolcanoes of the Virunga Range, some of which are Holocene in age. The Bufumbira rocks are noted for their unusual ultrapotassic chemistry.

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

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.
