Alutu (person)
Aluto (also known as Alutu) () is a dormant stratovolcano in Ethiopia, located in the Ethiopian Rift Valley in southern Oromia region between Lake Langano and Lake Ziway. It is the site of the Aluto–Langano Geothermal Power Station. Geology It features numerous vents along E-W and NNW-SSE trending fissures which converge at the coordinates of the volcano center, which is the center of a hypothesized caldera surrounded by rims, visible especially in the south and west. The largest vent is ''1 km × 0.5 km'' in size just SE of the volcano center and along the SE rim of the volcano. The volcano covers a surface area of appr. 25 km2. The silicic volcano center has an eruption history of more than 500,000 years, the last eruption was around 2400 years ago. Eruptions from Aluto may have influenced the dispersal of hominin populations in East Africa. Strong fumarolic activity continues throughout today. The volcano is permanently inflating and deflating with the str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ethiopia
Ethiopia, , om, Itiyoophiyaa, so, Itoobiya, ti, ኢትዮጵያ, Ítiyop'iya, aa, Itiyoppiya officially the Federal Democratic Republic of Ethiopia, is a landlocked country in the Horn of Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east and northeast, Kenya to the south, South Sudan to the west, and Sudan to the northwest. Ethiopia has a total area of . As of 2022, it is home to around 113.5 million inhabitants, making it the 13th-most populous country in the world and the 2nd-most populous in Africa after Nigeria. The national capital and largest city, Addis Ababa, lies several kilometres west of the East African Rift that splits the country into the African and Somali tectonic plates. Anatomically modern humans emerged from modern-day Ethiopia and set out to the Near East and elsewhere in the Middle Paleolithic period. Southwestern Ethiopia has been proposed as a possible homeland of the Afroasiatic langua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratovolcano
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Before Christ
The terms (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term is Medieval Latin and means 'in the year of the Lord', but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "''anno Domini nostri Jesu Christi''", which translates to 'in the year of our Lord Jesus Christ'. The form "BC" is specific to English and equivalent abbreviations are used in other languages: the Latin form is but is rarely seen. This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus, ''AD'' counting years from the start of this epoch and ''BC'' denoting years before the start of the era. There is no year zero in this scheme; thus ''the year AD 1 immediately follows the year 1 BC''. This dating system was devised in 525 by Dionysius Exiguus, but was not widely used until the 9th century. Traditionally, English follows Latin usage by placing the "AD" abbr ...

Ethiopian Rift Valley
The Great Rift Valley of Ethiopia, (or Main Ethiopian Rift or Ethiopian Rift Valley) is a branch of the East African Rift that runs through Ethiopia in a southwest direction from the Afar Triple Junction. In the past, it was seen as part of a "Great Rift Valley" that ran from Mozambique to Syria. Description The Great Rift Valley lies between the Ethiopian Plateau to the north and the Somalia Plateau to the south. The rift developed as the Nubian and Somali plates began to separate during the Miocene Period along the East African rift system. Rift initiation was asynchronous along the Ethiopian rift valley: deformation began around 18 million years ago at the south end, around 11 million years ago close to the Afar depression and probably around 6-8 million years ago in the central sector. The rift is extending in an ESE-WNW direction at about annually. The Ethiopian rift valley is about wide and bordered on both margins by large, discontinuous normal faults that give rise ...

Oromia Region
Oromia (Amharic: ) ( om, Oromiyaa) is a regional state in Ethiopia and the homeland of the Oromo people. The capital of Oromia is Addis Ababa. It is bordered by the Somali Region to the east; the Amhara Region, the Afar Region and the Benishangul-Gumuz Region to the north; Dire Dawa to the northeast; the South Sudanese state of Upper Nile, Gambela Region, South West Ethiopia Region, Southern Nations, Nationalities, and Peoples' Region and Sidama Region to the west; the Eastern Province of Kenya to the south; as well as Addis Ababa as an enclave surrounded by a Special Zone in its centre and the Harari Region as an enclave surrounded by East Hararghe in its east. In August 2013, the Ethiopian Central Statistics Agency projected the 2022 population of Oromia as 35,467,001; making it the largest regional state by population.

Lake Langano
Lake Langano ( Oromo: ''Hora Langaanoo'', Amharic: ላንጋኖ ሐይቅ) is a lake in the Oromia Region of Ethiopia, exactly 200 kilometers by road south of the capital, Addis Ababa, on the border between the East Shewa Zone and Arsi Zones. It is located to the east of Lake Abijatta in the Main Ethiopian Rift at an elevation of 1,585 meters. Overview According to figures published by the Central Statistical Agency, Lake Langano is 18 kilometers long and 16 km wide, with a surface area of 230 square kilometers and a maximum depth of 46 meters. The lake has a catchment 1600 square kilometers in size, and is drained by the Hora Kallo river which empties into the adjacent Lake Abijatta. As it is free of Bilharzia (schistosomiasis), unlike all other freshwater lakes in Ethiopia, Lake Langano is popular with tourists and city-dwellers. The lake is brown in colour and at first sight one may think that the lake is not clean. However this is not the case, the reason for the colour ...

Aluto–Langano Geothermal Power Station
The Aluto–Langano Geothermal Power Station, also known as Aluto Langano Geothermal Power Station, is the only geothermal power station in Ethiopia. Location The facility is located within the dormant Aluto volcano, a volcanic complex of the Ethiopian Rift valley trending NNW–SSE with several craters up to 1 km wide, between Lake Langano and Ziway. The site is approximately , by road, south of Addis Ababa, the largest city and capital of Ethiopia. The geographical coordinates of this power station in the Oromia Region are: 07°47'19.0"N, 38°47'41.0"E (Latitude:7.788611; Longitude:38.794722).

Geothermal Energy
Geothermal energy is the thermal energy in the Earth's crust which originates from the formation of the planet and from radioactive decay of materials in currently uncertain but possibly roughly equal proportions. The high temperature and pressure in Earth's interior cause some rock to melt and solid mantle to behave plastically. This results in parts of the mantle convecting upward since it is lighter than the surrounding rock. Temperatures at the core–mantle boundary can reach over 4000 °C (7200 °F). Geothermal heating, using water from hot springs, for example, has been used for bathing since Paleolithic times and for space heating since ancient Roman times. More recently geothermal power, the term used for generation of electricity from geothermal energy, has gained in importance. It is estimated that the earth's geothermal resources are theoretically more than adequate to supply humanity's energy needs, although only a very small fraction is currently being ...
