Sork Ale is a silicic stratovolcano located in the Danakil horst SE of Mallahle volcano. Sork Ale, also known as Asdaga, was constructed perpendicular to the NE-SW orientation of three larger stratovolcanoes of the Nabro volcanic range at the southern end of the Danakil Alps. A small, roughly 1-km-wide, 300-m-deep steep-walled caldera is found at the summit of the 1611-m-high volcano. Basaltic lava flows are prominent on the eastern side of the volcano, and satellite vents are located on the SE flank. The International Association of Volcanology and Chemistry of the Earth's Interior (1973) listed Sork Ale as probably active during the last 2000 years, but Wood (1980 pers. comm.) considered Holocene activity unlikely. The flanks of the volcano are extensively dissected on the SW to NE sides, but less dissected flows form the eastern-to-southern flanks.

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

The small, roughly 1-km-wide caldera at the western (left-hand) side of the circular, dark-colored lava field at the center of this NASA Landsat image lies at the summit of Sork Ale volcano. This 1611-m-high silicic stratovolcano, also known as Asdaga, was constructed perpendicular to the orientation of three larger stratovolcanoes trending NE-SW at the southern end of the Danakil Alps. The age of the most recent eruptions of Sork Ale is not certain.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
