Adwa, Ethiopia

Volcano Type: Stratovolcano
Volcano Status: Holocene
Last Known Eruption: Unknown
Summit Elevation: 1733 m    5,686 feet
Latitude: 10.070°N    10°4’12″N
Longitude: 40.840°E    40°50’24″E

Adwa, also known as Aabida, Amoissa, or Dabita, is a stratovolcano in the southern Afar area immediately east of Ayelu volcano. Adwa is younger than the vegetated Ayelu and is a stratovolcano with a 4 x 5 km caldera that originated following eruption of voluminous ignimbrites. A small 2.5-km-wide caldera cuts a trachytic dome extruded in the older caldera. Scoria cones are located on the floor of a circular summit caldera and on its NW and SW flanks. Extensive young basaltic lava flows cover the flanks of Adwa and overlap a sedimentary plain to the SE. Many fumaroles occur within the caldera of Adwa. Satellitic pyroclastic cones and lava domes were considered to be only a few hundred years old.

Dabbahu, Ethiopia

Volcano Type: Stratovolcano
Volcano Status: Historical
Last Known Eruption: 2005
Summit Elevation: 1442 m   4,731 feet
Latitude: 12.60°N   12°36’0″N
Longitude: 40.48°E   40°29’0″E

Dabbahu, also known as Boina, Boyna, or Moina, is a Holocene volcanic massif forming an axial range of the Afar depression SSW of the Alayta massif. Pantelleritic obsidian flows, lava domes, and pumice cones form the summit and upper flanks of the volcano, which rises above the Teru Plain and was built over a base of basaltic-to-trachytic lava flows of a shield volcano.

Erta Ale, Ethiopia

Volcano Type:      Shield volcano
Volcano Status:    Historical
Last Known Eruption:     2010 (continuing)
Summit Elevation:     613 m     2,011 feet
Latitude:     13.60°N     13°36’0″N
Longitude:     40.67°E     40°40’0″E

Erta Ale is an isolated basaltic shield volcano that is the most active volcano in Ethiopia. The broad, 50-km-wide volcano rises more than 600 m from below sea level in the barren Danakil depression. Erta Ale is the namesake and most prominent feature of the Erta Ale Range. The 613-m-high volcano contains a 0.7 x 1.6 km, elliptical summit crater housing steep-sided pit craters. Another larger 1.8 x 3.1 km wide depression elongated parallel to the trend of the Erta Ale range is located to the SE of the summit and is bounded by curvilinear fault scarps on the SE side. Fresh-looking basaltic lava flows from these fissures have poured into the caldera and locally overflowed its rim. The summit caldera is renowned for one, or sometimes two long-term lava lakes that have been active since at least 1967, or possibly since 1906. Recent fissure eruptions have occurred on the northern flank of Erta Ale.

Manda Hararo, Ethiopia

Volcano Type: Shield volcanoes
Volcano Status: Historical
Last Known Eruption: 2009
Summit Elevation: 600+ m   1,968 feet
Latitude: 12.17°N   12°10’0″N
Longitude: 40.82°E   40°49’0″E

The southernmost axial range of western Afar, the Manda Hararo complex is located in the Kalo plain, SSE of Dabbahu volcano. The massive complex is 105 km long and 20-30 km wide, and represents an uplifted segment of a mid-ocean ridge spreading center. A small basaltic shield volcano is located at the northern end of the complex, south of which is an area of abundant fissure-fed lava flows. Two basaltic shield volcanoes, the largest of which is Unda Hararo, occupy the center of the complex.

Lava Flow

Lava Flow

The dominant part of the complex lies to the south, where the Gumatmali-Gablaytu fissure system is located. Voluminous fluid lava flows issued from these NNW-trending fissures, and solidified lava lakes occupy two large craters. The small Gablaytu shield volcano forms the SE-most end of the Manda Hararo complex. Lava flows from Gablaytu and from Manda overlie 8000-year-old sediments. Hot springs and fumaroles occur around Daorre lake. The first historical eruption of Manda Hararo produced fissure-fed lava flows in 2007.
