These two photos – one false-colour the second natural-colour – are some of the first detailed pictures of the erupting vent and lava flows from the Nabro Volcano, located along the border between Eritrea and Ethiopia.
The first image is the false-colour image, and the red portions indicate hot surfaces, as you can imagine. Lava flows can be seen emerging north under the cover of ash, the leading edges hot enough to register in similar colours to the magma within the caldera itself. The bright blue clouds erupting out of the volcano are composed largely of escaping water vapour that condensed as the plume rose and cooled.
The second image is the natural-colour image, and shows a close-up view (as highlighted in the false-colour image by the white border around the volcano) of the volcanic plume and eruption site. The dark clouds to the right of the white clouds are ash plumes which are hovering directly above the volcano, while a partially cool lava flow is beginning to fill the crater to the north.
The images were taken on June 24 by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite.
Little is known about the eruption, with very few English-language reporters publishing any news on the eruption, despite displacing residents living near the volcano and disrupting flights in the region.
