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.

Last Known Eruption: 1820 (?)

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.

Volcano Type: Stratovolcano
Volcano Status: Historical
Last Known Eruption: 1957

The symmetrical Visoke volcano is the NE-most of a cluster of large stratovolcanoes at the southern end of the Virunga Range on the border of the Democratic Republic of Congo and Rwanda. The 3711-m-high stratovolcano contains a 450-m-wide lake in its summit crater. A NE-SW-trending fissure zone has produced many cinder cones NE of the trachyandesitic volcano. An eruption in 1957 formed two small cones on the north flank, 11 km from the summit.

The symmetrical Visoke volcano is the NE-most of a cluster of large stratovolcanoes at the southern end of the Virunga Range. The 3711-m-high stratovolcano contains a 450-m-wide lake in its summit crater (left center). Lobate lava flows descend the flanks of the volcano. A NE-SW-trending fissure zone has produced many cinder cones NE of the volcano (top). An eruption in 1957 formed two small cones on the north flank, 11 km from the summit.

Volcano Type: Volcanic field
Volcano Status: Radiocarbon
Last Known Eruption: 2000 BC
Summit Elevation: 3042 m 9,980 feet
Latitude: 12.95°N 12°57’0″N

Jebel Marra volcano is located in Darfur province, western Sudan, 200 km from the border with Chad, and about 100 km north of the town of Nyala. It is the second highest peak in Sudan. The Marra plateau covers 12,000 sq km from Tabago Hills to Tebella Plateau. The Marra plateau contains montane woodland.
The most prominent feature of the vast Jebel Marra volcanic field, located in the Darfur province of western Sudan, is the youthful Deriba caldera. The 5-km-wide, steep-walled caldera, located at the southern end of the volcanic field, was formed about 3500 years ago at the time of the eruption of voluminous airfall pumice and pyroclastic flows that traveled more than 30 km from the volcano.
