The 2011 eruption of Nabro is a continuing eruption of the Nabro stratovolcano in the Southern Red Sea Region of Eritrea( Ethiopia / Eritrea), which began on 12 June 2011 after a series of earthquakes.
The eruption has killed seven people and emitted the highest levels of sulfur dioxide (SO2) ever observed from earth orbit. The ash cloud from the eruption reached altitudes which disrupted airline traffic in the region
Until the eruption began, the volcano was thought to be extinct.
Dubbi last erupting in 1861 and Nabro remaining quiet for thousands of years
The erupting volcano is located within the Afar Triangle, in the larger Danakil Depression that holds many other active volcanoes. However, neither volcano thought potentially responsible for the eruption had been active in the past century, with Dubbi last erupting in 1861 and Nabro remaining quiet for thousands of years. No eruption of Nabro occurred before in recorded history.
