The massive Alayta shield volcano (center) covers an area of 2,700 km2 in the western Danakil depression SW of Lake Afrera (upper right). The volcanic consists of two parts--an elongated shield volcano on the west (medium-toned) and an extensive lava field forming the dark-colored area on the eastern flank of the shield volcano. The Alayta lava field, covered by very fresh lava flows (the most recent of which was erupted in 1907), was erupted from N-S-trending fissures and laps up against the western flank of Afderà volcano (immediately SW of Lake Afrera).

Alayta shield volcano (left-center) covers an area of 2,700 km2 in the western Danakil depression. A series of recent craters is aligned along the NNW-trending axis. The Alayta lava field (center dark area) was erupted from N-S-trending fissures along the E side of the volcano and reaches the W flank of Afderà volcano, immediately S of Lake Guilietti (Lake Afrera) at the upper right-center.

The Alayta shield volcano is in the center of this December 2019 Planet Labs satellite image mosaic (N is at the top; this image is approximately 82 km across), with a series of vents along the axis and darker lava flow fields surround much of the edifice. The flows reach Afderà to the NE. Lake Afrera is in the NE corner of the image.
