Geological Summary

The late-Plestocene to Holocene Bunyaruguru volcanic field, also known as the Kichwambe volcanic field, straddles the equator along the eastern side of the Western Rift Valley, south of Lake George. The Bunyaruguru volcanic field contains more than 130 maars, 27 of which contain lakes with water ranging from fresh to saline. Friable calcareous volcanic tuffs are inter-bedded with Pleistocene and Recent sediments. Only a few foiditic lava flows are found in the volcanic field. Although no dated eruptions are known, Reece (1955) noted that volcanic activity probably continued into historical times.

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

Photo Gallery

Maars of the Bunyaruguru volcanic field, also known as the Kichwambe volcanic field, blanket the center of this NASA Landsat image (with north to the top) of the eastern side of the Western Rift Valley. The Bunyaruguru field, lying south of the river channel connecting Lake Edward (left-center) and Lake George (top right), contains more than 130 explosion craters, 27 of which contain lakes with water ranging from fresh to saline. Maars of the Katwe-Kikorongo volcanic field lie across the river channel at the upper left.

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.
