Geological Summary

Yangudi volcano, lying in the Addado graben of the northern Ethiopian rift, is a complex rhyolitic stratovolcano with an elliptical summit caldera. A trachytic lava flow originating in the caldera covers part of the southern flank of Yangudi, also known as Angudi, Jangudi, or Langudi. Rhyolitic obsidian domes on the NW flank are surrounded by younger basaltic lava flows. Very recent scoria cones and lava flows are located south of Yangudi along the eastern graben faults.

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

Yangudi volcano is a complex rhyolitic stratovolcano with an elliptical summit caldera that lies near the center of this NASA Landsat image (with north to the top). Very recent scoria cones and lava flows form the dark-colored areas south and north of Yangudi along graben faults. Numerous NNE-SSW-trending faults parallel the Ethiopian Rift.

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.
