The Global Volcanism Program has no activity reports for East Zway.

The Global Volcanism Program has no Weekly Reports available for East Zway.

The Global Volcanism Program has no Bulletin Reports available for East Zway.

A large area of Recent-to-prehistorical basaltic cinder cones and lava flows lies immediately east and south of Lake Zway (also spelled Zwai, Zeway, and Ziway) and forms islands along the east shore of the lake. About 80 vents were formed along the East Zway segment of the Wonji Fault Belt. The youngest lava flows at East Zway are unaffected by the latest tectonic faulting along the Ethiopian Rift.

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

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.
