Geological Summary

The Katwe-Kikorongo volcanic field, stretching from the NE shore of Lake Edward to the western shore of Lake George, south of the Ruwenzori Range, is the most extensive of a series of volcanic fields in the Western Rift Valley of Uganda. The volcanic field, straddling the equator, covers an area of about 180 sq km and contains a group of about 80 foiditic tuff cones and maars, some of which are filled by lakes. Lake Katwe is a shallow 3-km-long body of water that occupies two of three intersecting craters immediately NE of Lake Edward. Local folk tales suggest that volcanism in the Katwe-Kikorongo area has continued into historical times.

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

Lake-filled and dry maars of the Katwe-Kikorongo volcanic field occupy the center of this NASA Landsat image (with north to the top). The volcanic field lies above the river channel connecting Lake Edward (lower left) with Lake George (upper right) in the Western Rift Valley of Uganda. Oblong, dark-colored Lake Katwe (lower left) is a shallow 3-km-long body of water that occupies two of three intersecting craters immediately NE of Lake Edward. Local folk tales suggest that volcanism in the Katwe-Kikorongo area has continued into historical times.

This lake-filled crater is part of the Katwe-Kikorongo volcanic field, which stretches from the NE shore of Lake Edward to the western shore of Lake George. It is the most extensive of a series of volcanic fields in the Western Rift Valley of Uganda containing carbonatitic tuff cones and maars, some of which contain lakes. Local folk tales suggest that volcanism in the Katwe-Kikorongo area has continued into historical times.

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.
