Mount Chilalo
Mount Chilalo is an isolated, extinct silicic volcanic mountain in southeastern Ethiopia. Its highest point (4036 m or 13,241 ft a.s.l.), in the Arsi Zone of the Oromia Region, is located in Arsi Mountains National Park on the border between the Hitosa and Tiyo woreda (). The mountain has an elliptical base (about 30 by 20 kilometers), whose major axis lies NNE-SSW or parallel to the predominant tectonic trend. Chilalo rises with gentle slopes for more than 1500 meters from the top of the plateau. At the summit, there is a large, almost circular caldera about 6 kilometers in diameter, whose southern rim is considered to be the mountain's summit. Mount Chilalo last erupted in the Pleistocene. One authority identifies Mount Chilalo as a late Trap Series volcano. The geologist Erik Nilsson claimed to have identified traces of glaciation on Chilalo, as well as on its neighbor Mount Kaka down to about 3400 meters, which he dated to the "Last Pluvial Period".Erik Nilsson"Traces of A ...

Arsi Zone
Arsi ( om, Godina Arsii) is a zone in Oromia Region of Ethiopia, named after a clan of the Oromo, who inhabit in the area. Arsi is bordered on the south by Bale Zone, on the southwest by the West Arsi Zone, on the northwest by East Shewa Zone, on the north by the Afar Region and on the east by West Hararghe Zone. It covers an area of 19,825.22 km2, divided into 25 districts (''weredas''). The population was officially estimated at 3,894,248 in mid 2022. The highest point in Arsi Zone is Mount Chilalo; other notable mountains in this zone include Mount Kaka and Mount Gugu. Arsi Mountains National Park was created in 2011 to protect a section of the mountains. The administrative centre of this zone is in Asela, with an estimated 139,537 inhabitants in mid 2022; other towns in this zone (with estimated populations in mid 2022) include Bokoji (36,805) in Limuna Bilbilo District, Robe (31,445) in Robe District, Etaya (31,094) in Hitosa District, Dera (30,676) in Dodota District, Ab ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Ethiopian Highlands
The Ethiopian Highlands is a rugged mass of mountains in Ethiopia in Northeast Africa. It forms the largest continuous area of its elevation in the continent, with little of its surface falling below , while the summits reach heights of up to . It is sometimes called the Roof of Africa due to its height and large area. Most of the Ethiopian Highlands are part of central and northern Ethiopia, and its northernmost portion reaches into Eritrea. History In the southern parts of the Ethiopian Highlands once was located the Kingdom of Kaffa, a medieval early modern state, whence the coffee plant was exported to the Arabian Peninsula. The land of the former kingdom is mountainous with stretches of forest. The land is very fertile, capable of three harvests a year. The term ''coffee'' derives from the ar, قهوة, italic=no ()''Oxford English Dictionary'', 1st ed. "coffee, ''n.''" Oxford University Press (Oxford), 1891. and is traced to Kaffa.

East African Rift
The East African Rift (EAR) or East African Rift System (EARS) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. In the past it was considered to be part of a larger Great Rift Valley that extended north to Asia Minor. A narrow zone, the rift is a developing divergent tectonic plate boundary where the African Plate is in the process of splitting into two tectonic plates, called the Somali Plate and the Nubian Plate, at a rate of 6-7 mm per year. The rift system consists of three microplates, the Victoria Microplate to the north, and the Rovuma and Lwandle microplates to the south. The Victoria Microplate is rotating anti-clockwise with respect to the African plate. Its rotation is caused by the configuration of mechanically weaker and stronger lithospheric regions in the EARS. Extent A series of distinct rift basins, the East African Rift System extends over thousands of kilometers. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glaciation
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period ...

Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish language, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Woreda
Districts of Ethiopia, also called woredas ( am, ወረዳ; ''woreda''), are the third level of the administrative divisions of Ethiopia – after ''zones'' and the '' regional states''. These districts are further subdivided into a number of wards called ''kebele'' neighbourhood associations, which are the smallest unit of local government in Ethiopia. Overview Districts are typically collected together into zones, which form a region; districts which are not part of a zone are designated Special Districts and function as autonomous entities. Districts are governed by a council whose members are directly elected to represent each ''kebele'' in the district. There are about 670 rural districts and about 100 urban districts. Terminology varies, with some people considering the urban units to be ''woreda'', while others consider only the rural units to be ''woreda'', referring to the others as urban or city administrations. Although some districts can be traced back to earli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
