Overview

A large unnamed area of Holocene basalts and a possible small cinder cone is located on the floor of the Ethiopian Rift Valley SW of Tullu Moje volcano. The flows occupy a NE-SW-trending zone near the active eastern margin of the rift valley, E of Lake Ziway and NW of the massive Pleistocene Ch'llalo (Cilallo) volcano, one of the largest edifices of the central Ethiopian Rift Valley.

Regional Volcanic Activity

The Eastern Africa Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

A large unnamed area of young basaltic lava flows and a possible small cinder cone is located on the floor of the Ethiopian Rift Valley SW of Tullu Moje volcano, which produced the dark-colored obsidian lava flow at the top-center of this Landsat image. The basaltic flows occupy a NE-SW-trending zone near the active eastern margin of the rift valley, NE of Lake Zwai (lower left) and NW of the 4,000-m-high Pleistocene Ch'llalo (Cilallo) volcano (lower right).
