Overview

Dubbi, located east of the Erta Ale Range and south of the crystalline basement rocks of the Danakil Alps, is a large volcanic massif that rises above the western shore of the Red Sea. About 20 small cinder cones are located at the summit, and extensive basaltic lava fields to the north and NE, known as the Edd lava field, cover an area of 2700 km2 and reach the Red Sea coast. The two most-recent eruptive centers are fissure systems that extend NW-SE and NNE-SSW.

The former produced lava flows that reached the Red Sea in 1400 CE. The second created 19 small craters at the summit in 1861. Ash fell more than 300 km from the volcano.

Two villages were destroyed and more than 100 people were killed during Africa's largest eruption in historical time. Lava flows from the 1861 eruption traveled as far as 22 km and reached the coast.

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

Dark-colored lava flows radiate away from the summit of Dubbi volcano in this Space Shuttle image with the Red Sea at the upper right. The two most recent eruptions were fed by fissure systems that extend NW-SE and NNE-SSW. The former produced lava flows that reached the Red Sea in 1400 CE. Lava flows from the 1861 eruption traveled as far as 22 km to the east and also reached the coast.
