Geological Summary

Katunga, an isolated tuff cone with associated lava flows located east of Lake Edward, is the southernmost feature of a N-S-trending chain of high-potassium foditic volcanic fields in the Western Rift Valley of Uganda. Katunga is the type locality of the rock type katungite, an olivine-melilitite. The undissected tuff cone was erupted through metamorphic basement rocks and its rim and flanks are blanketed with ejected schists. Katunga contains a freshwater lake in its summit crater. Two lava flows traveled to the NE from vents on the north and NE flanks. The age of the cone is uncertain, but it is contemporaneous with late-Pleistocene to Recent tuff cones in the Bunyaruguru area, and the undissected condition of the tuff cone and associated lava flows implies a young age.

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