Aerial Photos of the Rift Valley volcanosThe photos below were taken during a survey and transport flight by helicopter south of Erta Ale on 16.2.2002 and on 19.2.2002 north of
Erta Ale. |
![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/ja_010.jpg) Life prevails: A fresh lava flow has stopped just short of this isolated patch of greenery on Erta Ale's southern slopes. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/ja_063.jpg) Lonely spatter cones within a field of pahoehoe lava south of Erta Ale. Note fissures in foreground and behind the cones. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/ja_080.jpg) Chain of spatter cones surrounded by sand dunes mark the orientation of the East African rift valley. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/mf_037.jpg) Field of sand dunes between Erta Ale and Giulietti salt lake. |
![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/mf_040.jpg) Chain of spatter cones (foreground) from a linear eruption between Erta Ale and Hayli Gubbi. Note fault scarp parallel and behind the alignment. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/mf_041.jpg) Hayli Gubbi, 521 m. This volcano emitted a steam column on 15.02.2002 but seemed quiet during our survey flight. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/ja_082.jpg) These cinder cones near Hayli Gubbi have been dissected very recently by numerous faults which run parallel to the East African rift. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/mf_042.jpg) Hayli Gubbi summit crater inside a larger caldera. Note the fault scarp on the caldera's wall on the right. |
![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/ja_069.jpg) Hayli Gubbi summit crater. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/ja_078.jpg) Evaporation of water from Giulietti salt lake has produced salt crystals which now float on the lake surface. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/ja_075.jpg) Salt marsh along the northwestern coast of Giulietti salt lake. Colors are caused by algae. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/mf_038.jpg) Borawli volcano (821 m) on the shore of Lake Giulietti. |
![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/ja_079.jpg) Afdera volcano (1295 m) rises behind Lake Giulietti. The low cinder cone in the foreground was possibly caused by phreatic explosions when lava flows entered the lake. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/ja_072.jpg) Note that this interesting cinder cone near Lake Giulietti is dissected by razor-sharp faults. They run almost exactly along the line of sight (a bit to the left). Do not confuse them with the wider erosion gullies. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/mf_073.jpg) Gada Ale (287 m). Lake Aasale (approx. 116 meters below sea level) in the background. Note numerous fissures in the right foreground. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/mf_072.jpg) A jewel in the desert: Small salt lake and minute patch of vegetation on it's shore inside a cinder cone south of Lake Aasale. |
![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/mf_071.jpg) Dalaffilla/Alu (613 m) and Alu fissure vents (429 m) in the foreground. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/mf_070.jpg) Borale Ale (668 m) | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/mf_184.jpg) Above the shore of Lake Aasale. | ![Aerial Photos of the Rift Valley volcanos Aerial Photos of the Rift Valley volcanos](air/icons/mf_183.jpg) Lake Aasale (approx. 116 meters below sea level) and river delta in the forground. |
