Geological Summary

The Korath Range is an isolated group of tuff cones and lava flows in southern Ethiopia that were erupted along the Turkana Rift, which extends north from Kenya. About 20 tuff cones occupy the Korath Range, many of which issued lava flows from their flanks that traveled up to about 5 km. The apparent youngest flow issued from the central crater and flowed through a breach in its rim. The absolute age of the dominantly basanitic-tephritic lava flows is unknown, but a shell adhering to the youngest flow was radiocarbon dated at 7900 years before present (BP) (Brown et al., 1969). Davidson (1983) indicated an age between 30,000 BP and 7900-9500 BP.

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

The fissure-controlled Korath Range is an isolated group of tuff cones and lava flows in southern Ethiopia that were erupted along the Turkana Rift. The Korath Range tuff cones issued many lava flows that traveled up to about 5 km, forming lobate margins, most prominently on the western flanks of the massif. The apparent youngest flow issued from the central crater and flowed through a breach in its rim.

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.
