Erta Ale Range
Erta Ale Range is the most important axial volcanic chain of the Afar Depression, Afar Region, Ethiopia. It consists mostly of shield volcanoes. The active volcano Erta Ale is a prominent feature of the range. The highest volcano of the range is Ale Bagu, with an elevation of above sea level. Other named peaks (with their elevations) include Alu (Ethiopia), Alu (), Dalaffilla () and Borale Ale (). Erta Ale This volcano of Erta Ale is the most active in Ethiopia and rises to at its highest point. It is one of many shield volcanoes in the area and is wide with a elliptical summit containing many steep pit pit crater, craters. Its perpetually active pit craters are renowned for their churning lava lakes.

Erta Ale
Erta Ale (or Ertale or Irta'ale; Amharic: ኤርታሌ) is a continuously active basaltic shield volcano in the Afar Region of northeastern Ethiopia, which is itself part of the wider Afar Triangle (a barren desert region straddling Djibouti, Ethiopia and Eritrea). The volcano is located in the Danakil Depression, an area on the border between Ethiopia and Eritrea that is below sea level. It is the most active of the volcanoes in Ethiopia. Geology Erta Ale is high, with one or sometimes two active lava lakes at the summit which occasionally overflow on the south side of the volcano. It is notable for holding the longest-existing lava lake, present since at least 1906.Barnie, T.D., Oppenheimer, C., and Pagli, C. (2016). Magmatic Rifting and Active Volcanism. Geological Society, London, Special Publications, 420, 181–208. https://doi.org/10.1144/SP420.15 Volcanoes with lava lakes are rare: there were only eight in the world reported in 2019.

Borale Ale
Borale Ale is a stratovolcano located in the Great Rift Valley, Ethiopia. It is part of the Erta Ale Volcanic Segment in the northern Afar Region of Ethiopia, which contains seven volcanoes including Erta Ale Erta Ale (or Ertale or Irta'ale; Amharic: ኤርታሌ) is a continuously active basaltic shield volcano in the Afar Region of northeastern Ethiopia, which is itself part of the wider Afar Triangle (a barren desert region straddling Djibouti, ..., Alu, and Dalafilla. The mountain consists of two structures: a stratovolcano reaching 625 meters in elevation, surrounded by a shield volcano composed dominantly of fissural lavas.

Mountain Ranges Of Ethiopia
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains ...

Geography Of Ethiopia
Ethiopia is located in the Horn of Africa. It is bordered by Eritrea to the north, Djibouti and Somalia to the east, Sudan and South Sudan to the west, and Kenya to the south. Ethiopia has a high central plateau, the Abyssinian Highlands (or Ethiopian Highlands) that varies from above sea level, with some 25 mountains whose peaks rise over 4,000 meters (13,200 ft), the highest being Ras Dashen at 4,543 meters (14,538 ft). Elevation is generally highest just before the point of descent to the Great Rift Valley, which splits the plateau diagonally. A number of rivers cross the plateau; notably the Blue Nile rising from Lake Tana. The plateau gradually slopes to the lowlands of the Sudan on the west and the Somali-inhabited plains to the east. Ethiopia's westernmost locality is Pibor River opposite the Sudanese village of Denjok. Its easternmost locality lies along the eastern border of Dollo Zone opposite Puntland and Galmudug states.

Danakil Alps
The Danakil Alps are a highland region in Ethiopia and Eritrea with peaks over 1000 metres in height and a width varying between 40 and 70 kilometres. The area is known in the Afar language as Arrata. The alps lie along the southern Red Sea to the east of the Danakil Depression and separate it from the sea. The alps are asymmetric in cross-section with a comparatively gentle rift escarpment facing the Red Sea and intense normal faulting on the inland side. In the northern part of the alps the basement rock is less elevated and there are many volcanic edifices, such as those forming the Nabro Volcanic Range. The largest of the Nabro Volcanic Range edifices are the Mallahle, Nabro, and Dubbi. The volcanic range extends northwestward to the Red Sea, ending with the Kod Ali volcano offshore. The Danakil Alps have been cut off from the sea since the late Pleistocene. Composition Geologically these highlands are described as a horst and are sometimes referred to as the Danakil H ...

Lava Lakes
Lava lakes are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. The term is used to describe both lava lakes that are wholly or partly molten and those that are solidified (sometimes referred to as ''frozen lava lakes''). Formation Lava lakes can form in three ways: *from one or more vents in a crater that erupts enough lava to partially fill the crater; or *when lava pours into a crater or broad depression and partially fills the crater; or *atop a new vent that erupts lava continuously for a period of several weeks or more and slowly builds a crater progressively higher than the surrounding ground. Behaviors Lava lakes occur in a variety of volcanic systems, ranging from the basaltic Erta Ale lake in Ethiopia and the basaltic andesite volcano of Villarrica, Chile, to the unique phonolitic lava lake at Mt. Erebus, Antarctica. Lava lakes have been observed to exhibit a range of behaviours. A "constantly circula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pit Crater
A pit crater (also called a subsidence crater or collapse crater) is a depression formed by the sinking or collapse of the surface lying above a void or empty chamber, rather than by the eruption of a volcano or lava vent. Pit craters are found on Mercury, Venus, Earth, Mars, and the Moon. Pit craters are often found in a series of aligned or offset chains; in these cases, the features is called a ''pit-crater chain''. Pit-crater chains are distinguished from catenae or crater chains by their origin. When adjoining walls between pits in a pit-crater chain collapse, they become troughs. In these cases, the craters may merge into a linear alignment and are commonly found along extensional structures such as fractures, fissures, and graben. Pit craters usually lack an elevated rim as well as the ejecta deposits and lava flows that are associated with impact craters.Okubo, Chris, and Stephen Martel.

Dalaffilla
Dalaffilla, also called Gabuli, or Alu-Dalafilla is a high stratovolcano in Ethiopia. It is the highest point of Gulina. The only recorded eruption of Dalaffilla occurred in 2008 when lava flows from its western and northwestern flanks traveled to the northeast. Dalafilla is part of the Erta Ale Volcanic Segment in the northern Afar Region The Afar Region (; ; ), formerly known as Region 2, is a Regions of Ethiopia, regional state in northeastern Ethiopia and the homeland of the Afar people.

It has a shallow gradient in its lower section, but the upper portion of the volcano is extremely steep.

Alu (Ethiopia)
Alu is a system of volcanic fissures, located in Ethiopia. The fissures have produced silicic lava flows, and other fissures south of the volcano have been the source of huge youthful basaltic lava flows, which enlarge to the north as far as Lake Bakili.

Ale Bagu
Ale Bagu is a stratovolcano located in the Afar Region, Ethiopia. It is the highest volcano of Erta Ale Range. The village of El Dom sits at the base of Ale Bagu. Ale Bagu is a rare example of a mountain with a prominence higher than its elevation figure. This is due to the key col being below sea level.
