	(GCB5D7) Erta Ale Volcano by Klammeraffe
		Erta Ale (the Fuming or Devil's Mountain) lies in the north-east end of The Rift Valley segment that runs across Ethiopia and Djibouti to the Red Sea.
		Erta Ale and its neighbours have grown from the most low lying part of the Great Rift Valley on land.
		The lava of Erta Ale is basaltic, which remains molten at 1100°C. The lava lake has a surface area of 4 000 sq m, so the thermal radiation is intense.

		Please note that the measurement error of the rims is about 15m, shifting the lines to the outside of the caldera and the craters due to the necessary safety distance to be held towards the rims.
		GPS receiption was excellent due to the exposed nature of Erta Ale, where signals are shaded only when the receiver is close to the caldera wall inside the caldera.

		Erta Ale is a shield volcano, located in the Afar depression at 13.6°N, 40.67°E, 613m (location map).
		oday we crossed the final stretch of desert to the base of Erta Ale, as the above pictures show, it wasn't without problems......at one point we had two vehicles stuck in the sand at once, We are at Dodom camp and tonight we climb to the crater on camels.
		When we arrived at Erta Ale on the 26th Feb the lava lake was inactive and solid, in the centre were 3 hornitos rising up about 8 to 10 metres from the now solid lava lake, these hornitos degassed loudly, spat out very small amounts of material and glowed faintly at night.

	ERTA ALE
		Erta' Ale is an enormous volcanic edifice stretching over 30 km according to an axis parallel to the great rift, and culminates to approximately 700m above the Danakil depression.
		The last thermal measurements collected at the Erta' Ale were those carried out in the seventies by Tazieff's team, while the most recent temperature reported in the literature are those obtained by infra-red measurements using satellites (work mainly carried out by Oppenheimer, Francis and Rothery).
		An active lava lake such as found at the Erta' Ale consists of a volume of magma in convective circulation renewed permanently by a major source of magma.

		Erta Ale ist ein Schildvulkan der sich in der Danakilsenke in Nordost Äthiopien, der durch seine Abgeschiedenheit, extremes Klima, und die Präsenz oft feindseliger Afar Stammesangehöriger, selten besucht wird.
		Als sich die Möglichkeit ergab mich der Expedition anzuschließen, war die Entscheidung natürlich einfach.
		Auf dem Weg dorthin überflogen wir Borale Ale (Fig.5a), Dalaffilla (Fig.5b), Alu (Fig.5c) und Gada Ale (Fig.5d) Vulkane, sowie den Elizabeth Kegel (Fig.5e) die aus der riesigen Salzfläche der Senke herausragen, bevor wir über die verlassene italienische Minensiedlung (Fig.5e) flogen und zwischen den heißen Quellen landeten (Fig.5g).

		Kilauea is reported as a “hot spot,” Erta’ Ale is listed as a divergent plate volcano, and Momotombo is indicated to be a volcano typical of a convergent plate boundary.
		It is important to note that in all three of the volcanoes (Kilauea, Erta’ Ale, Momotombo) described by the USGS (2006), the volume percent of water is 37.1%, 77.2%, and 97.1% respectively.
		C0 is the next major gas present, and, as a matter of fact, constitutes a greater percentage of the volcanic gases present in Kilauea than water vapor.

	Remote sensing of heat, lava and fumarole emissions from Erta'Ale volcano, Ethiopia (Site not responding. Last check: 2007-10-26)
		Erta 'Ale volcano, sited within the Afar Triangle of Ethiopia, is one of the least frequented, perennially active, subaerial volcanoes.
		By compiling a time series of Landsat MSS and TM, JERS-1, SPOT, and AVHRR digital imagery, and space-borne photographic data, we have been able to constrain the activity of this volcano, important for its geodynamic setting, during the long period since 1974 when volcanological investigations effectively ceased.
		Existing techniques for infrared thermometry have been modified to cope with saturation of the short wavelength infrared Landsat TM band 5 and 7 sensors, enabling derivation of thermal fluxes from Erta 'Ale's active lava lakes.

		A Mulit-Temporal Analysis of the Erta Ale Volcano in Ethiopia Using Space Based Imagery
		Erta Ale is a remote, continually erupting desert volcano in Ethiopia located at 13.60?N, 40.67?E. The remoteness and the political instability of the region have made satellite remote sensing the only way to retrieve data on this volcano from 1976 till 1992.
		This paper will review the geology of the volcano, the basics of volcano remote sensing, and will compare the Corona satellite photographs of the 1960's to the modern views of Erta Ale from SIR-C, Landsat, and on-site images.
