The NaBrO is a 2218 -meter-high stratovolcano in Eritrea on the Red Sea. It is the highest volcano in the Danakil desert geologically active, which borders Ethiopia and part of the Afar Triangle, which in turn is part of the East African Rift.
The NaBrO forms a double caldera system, in which a caldera has a diameter of five kilometers and the other a diameter of eight kilometers. In the craters rhyolitic lava domes and basaltic lava flows were discovered.
Mid-June 2011 broke out of the volcano, and thus ended a rest period of unknown duration.
As part of a series of earthquakes, which reached a magnitude of 5.7 on the part, it came on the morning of June 13, 2011 about 01:00 clock CEST to an outbreak that was first attributed to the nearby Dubbi. Due to the ash cloud of the air traffic in East Africa has been affected.
The area in which the NaBrO is, is weakly populated border area between Ethiopia and Eritrea; an existing volcano in nearby road is considered unsafe. About major loss episodes initially was not known.
