The Anabro (Nabro) volcano in the Northern Red Sea Region of Eritrea has erupted sending an ash plume more than 13.5 kilometres into the sky and disrupting air traffic across eastern Africa.

Part of the Afar Triangle, the stratovolcano is one of many volcanic caldera complexes in the north easternmost part of the East African Rift valley region. Nabro is located in the Danakil Depression, close to Eritrea’s border with Ethiopia and north of Djibouti, and has not erupted in at least 150 years. It is the most prominent of 3 large volcanoes (Nabro, Dubbi, Mallahle) in the region, each containing a large summit caldera.

The volcano erupted at 2103 GMT Sunday evening. The Volcanic Ash Advisory Center (VAAC) said Monday that the 5,331 ft volcano has resulted in a large ash plume of up to 13.5 kilometres (8 miles) high.  The scale of the eruption, compared to the ongoing eruption in Chile and 2010′s eruption at Eyjafjallajökull in Iceland, remains unclear.

The eruption was preceded by seven moderate earthquakes yesterday afternoon. A 5.6 magnitude quake at 21.03 GMT signalled the start of the eruption. The quake was centred 48 km south of the town of  Edd (pop 11,259) and 199 km southwest of the city of Al-h’udaydah (pop 617,871). A 4.6 magnitude quake followed less than 35 minutes later.
