At the top left, the capital city of Sudan, Khartoum, is located at the convergence of the Blue Nile and the White Nile rivers. Although the Blue Nile is much shorter than the White Nile, it contributes about 80% of the flow of the river. The Dahlak Archipelago is seen off the Red Sea coast of Eritrea. North of the Rift Valley, in central Ethiopia, are the Simien Mountains and Lake Tana. Lake Tana is the source of the Blue Nile. Photo courtesy of NASA.
The stratovolcano Nabro rumbled to life on 12 June 2011 in Eritrea, after a series of earthquakes. This satellite image was taken the following day. There had been no previous reports of eruptions at Nabro. Photo courtesy of NASA.
Astronaut photo of Nabro in Eritrea, taken four and a half months before the June 2011 eruption. Before its 2011 eruption, the volcano was widely believed to be extinct. Image courtesy of NASA.
Satellite view of the Nabro volcano in Eritrea, taken on 24 June 2011. The bright red areas indicate hot surfaces. Hot volcanic ash glows above the vent, located in the center of Nabro’s caldera. To the west of the vent, portions of an active lava flow are also hot. The speckled pattern on upstream portions of the flow are likely due to the cool, hardened crust splitting and exposing fluid lava as the flow advances. The bulbous blue-white cloud near the vent is likely composed largely of escaping water vapor that condensed as the plume rose and cooled. The wispy, cyan clouds above the lava flow are evidence of degassing from the lava. Image courtesy of NASA.
View of the Nabro volcano in Eritrea on 29 June 2011 shows the extent of the lava flow and the diminished intensity of the eruption. The eruption continued for many more weeks. Image courtesy of NASA.
