Geological Summary

Dama Ali is a broad shield volcano that rises above the NW shore of Lake Abbe (also known as Lake Abhe) in eastern Ethiopia. The 25-km-wide volcano was constructed at the southern end of the Kalo Plain. Nested circular craters are located at the summit of the dominantly basaltic volcano, which also displays an older caldera rim. An arcuate chain of rhyolitic lava domes occupies the northern, western, and southern flanks. Youthful basaltic lava flows surround these domes and blanket the flanks of the volcano, and recent flows cover the young sediments of the Kalo and Abhe basins. The Asmara basaltic pyroclastic cone located in the southern Kalo basin SW of the base of the volcano was considered to have had activity during the last 2000 years (International Association of Volcanology and Chemistry of the Earth's Interior, 1973). It is considered the most likely source of an eruption reported to have occurred in 1631 (Gouin, 1979). Major fumarolic activity occurs in the summit crater, and abundant hot springs are found on the volcano.

Dama Ali is a broad shield volcano that rises above the NW shore of Lake Abhe (right) at the southern end of the Kalo Plain and was the most likely source of an eruption reported to have occurred in 1631 AD. Nested circular craters are located at the summit of the dominantly basaltic volcano, and an arcuate chain of rhyolitic lava domes can be seen on the northern, western, and southern flanks. Major fumarolic activity occurs in the summit crater, and abundant hot springs are found on the volcano.

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.
