East Zway

East Ziway

Fissure vent · Ethiopia · 1889m

A large area of Holocene 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.

Geological summary

A large area of basaltic cinder cones and lava flows lies within about 5 km of the SE shore of Lake Ziway, and also forms islands along its E shore. About 80 vents were formed along the East Ziway segment of the Wonji Fault Belt. The youngest lava flows have been unaffected by the latest tectonic faulting along the Ethiopian Rift.
