Summary of Holocene eruption dates and Volcanic Explosivity Indices (VEI).
|Start Date||Stop Date||Eruption Certainty||VEI||Evidence||Activity Area or Unit|
|0050 BCE (?)||Unknown||Confirmed||Radiocarbon (uncorrected)|
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.

|Alutu volcano lies between light-brown Lake Mirrga (Lake Langano) on the south and greenish Lake Zway on the north. The volcano displays several craters aligned along NNE-SSW and E-W fissures. Dark-colored obsidian lava flows erupted from craters along the fissures have descended the flanks in all directions. Although the age of the most recent eruption of Alutu is not known, its eruptive products overlie recent basaltic lava flows to the west, and strong fumarolic activity continues.

|A large area of Holocene-to-prehistorical cinder cones and lava flows lies immediately east and south of Zway Lake (bottom) and forms islands along its eastern shore in this NASA Landsat mosaic (with north to the top). Faulting along the East Zway segment of the Wonji Fault Belt is seen cutting horizontally across the bottom of the image. The dark-colored Alutu volcanic complex lies the lower left. The 15 x 30 km wide Zway (also spelled Zwai, Zeway, or Ziway) lake occupies the central Ethiopian Rift.

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.
