Overview

The Manda Gargori rift, located north of the town of Aisa Aita NE of Borawli volcano and SE of Kurub volcano, is the youngest rift segment in the Afar depression and is only one third the width of the adjacent Manda Hararo-Goba'ad rift system to the west. Two older lava flows from the Manda Gargori rift have Pleistocene potassium-argon dates. Youthful-looking lava flows, some of which may have been subaqueous, have been emitted from NNW-trending fissures.

A hyaloclastite tuff ring is also present, and a rhyolitic lava dome surrounded by two basaltic lava flows is located north of Uddummi lake. No historical activity has been reported at the dominantly basaltic Manda Gargori rift, but human footprints have been observed in a fresh ashfall deposit, and the eruptive activity is considered to be of historical age.

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

Scoria cones and lava flows of the Manda Gargori rift are seen across this December 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 9.5 km across).The rift is one of the younger segments in the Red Sea area and NW-SE trending faults are visible through the image. Ridges of older lava flows are visible between the lighter-colored sediment. A tuff ring is visible south of the younger lavas.
