Geological Summary

Gada Ale, also known as Kebrit Ale, is the most prominent volcano at the northern end of the Erta Ale Range. It is formed of interstratified lava flows and hyaloclastites. Fumarolic activity is continuing, and a small lake filled by boiling mud occupies the crater. Like other Erta Ale Range volcanoes, Gada Ale is considered to be of Holocene age (Barberi and Varet, 1970). A fissure on the SE flank has produced spatter cones and a cinder cone; the latter fed lava flows that reach to Lake Bakili. The symmetrical Catherine tuff ring is located along this same SE trend west of Lake Bakili, and other tuff rings occur on the east side of the lake. A 2-km-wide salt dome west of Gada Ale has uplifted lava flows as much as 100 m, and the structure of Gada Ale itself also appears to be related to salt diapir uplift.

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

Gada Ale (upper right) is the most prominent volcano at the northern end of the Erta Ale Range. The 287-m-high volcano is seen here from the south, with two small lakes on its lower NW flank. Lake Aasale (Lake Karum), whose surface lies about 116 meters below sea level, is in the background. Prominent fissures (lower right) are adjacent to an uplifted salt dome (lower left). Salt diapir uplift has affected both this 2-km-wide area west of the volcano (where lava flows are uplifted as much as 100 m) and Gada Ale itself.

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.
