The massive Atakor volcanic field is the largest in the Hoggar (or Ahaggar) volcanic province of southern Algeria and covers an area of 2150 sq km. Basaltic (mostly basanitic) scoria cones and lava flows of Pleistocene-Holocene age lie near spectacular older trachytic and phonolitic lava domes and volcanic necks that form some of the most dramatic scenery of northern Africa. The latest stage of activity began around 1.95 million years and continued almost to the present.
Lava flows cover Holocene lake sediments dated at about 10,000 year Before Present (BP) and alluvial terraces in which Neolithic artifacts have been found. Historical pottery has been found within lava flows in the Tahifet area, and oral traditions of the Tuareg people also suggest that eruptions were witnessed. Sporadic fumaroles and persistent small-scale seismicity has been noted during historical time.

Numerous phreatic explosion craters dot the Salt Plain NNE of the Erta Ale Range in one of the lowest areas of the desolate Danakil depression. These craters mark Earth’s lowest known subaerial volcanic vents. The most recent of these craters, Dallol, lies 48 m below sea level and was formed during an eruption in 1926. Colorful hot brine springs are found in the Dallol area.

The In Ezzane volcanic field lies in SE Algeria, near the border with Niger. The alkaline In Ezzane volcanic field, part of which extends into Niger, covers about 500 sq km at the eastern end of Hoggar (Ahaggar) volcanic province and was assigned a Recent age (Liegeois et al., 2005). This poorly known and isolated volcanic field erupted through basement rocks at the western end of the Saharan meta-craton.

Volcano Type: Stratovolcano
Volcano Status: Historical
Last Known Eruption: 1820 (?)

Longitude: 39.93°E 39°56’0″E
Fentale, also known as Fantale, is a large stratovolcano at the northern end of the Main Ethiopian Rift. It consists primarily of rhyolitic obsidian lava flows with minor tuffs. Welded pantelleritic ash flows accompanied formation of a 2.5 x 4.5 km summit caldera, which has steep-sided walls up to 500 m high. The WNW-ESE-trending elliptical caldera has an orientation perpendicular to the Ethiopian Rift, and post-caldera vents occur along the same orientation. Trachytic and obsidian lava flows occur on the caldera floor, and fresh-looking lava flows descend the flanks from satellitic vents. An eruption from Fentale during the 13th century destroyed an Abyssinian town and church south of the volcano. In 1820 basaltic lava flows were extruded onto the Main Ethiopian Rift from a 4-km-long fissure on the south flank, and lava flows were erupted on the floor of the caldera.
