Giulietti
Lake Afrera (in Italian Lake Giuletti) is a hypersaline lake in northern Ethiopia. Located in Kilbet Rasu, Afar Region, it is one of the lakes of the Danakil Depression. According to its entry in Lakenet, it has a surface area of , although another source states the area is .Robert Mepham, R. H. Hughes, and J. S. Hughes''A directory of African wetlands'' (Cambridge: IUCN, UNEP and WCMC, 1992), p. 168 An unconfirmed report gives its depth as ; the lake is fed by underground streams. It is also known as Lake Giulietti, the name Raimondo Franchetti gave it after the Italian explorer Giuseppe Maria Giulietti was slain by Afars southwest of the lake. Another name for this body of water is Lake Egogi (or Egogi Bad), which is the name L. M. Nesbitt's Afar guide gave it when the Italian explorer became the first European to see it in 1928. The single island in Lake Afrera, Franchetti Island (also known as "Deset"), located in the southern part of the lake, is considered the lowest-lyi ...

Giuseppe Maria Giulietti
Giuseppe Maria Giulietti (28 December 1847 – 25 May 1881) was an Italian soldier, geographer and explorer. He was born in a wealthy family in Casteggio, province of Pavia. He enrolled in the Corpo Volontari Italiani (Italian Volunteers Corps) which fought against the Austrians in 1866, during the Italian independence wars. Later he was called by Giacomo Doria for his expedition to save the Antinori expedition in Shewa, a principality of Ethiopia. Afterwards he led several explorations in that country. During the last of them, he was killed by the Afar tribes, together with Ettore Biglieri and thirty-one seamen of the ship '' Ettore Fieramosca'' in the southern Afar Depression. The location of the massacre was identified by L.M. Nesbitt and his two Italian associates as the Tio waterhole in 1928, who erected a cairn to mark the spot. The explorers were then threatened by the local Afar who believed that they would then exact revenge for the deaths over a generation ago, and Ne ...

Afar Depression
The Afar Triangle (also called the Afar Depression) is a geological depression caused by the Afar Triple Junction, which is part of the Great Rift Valley in East Africa. The region has disclosed fossil specimens of the very earliest hominins; that is, the earliest of the human clade, and it is thought by some paleontologists to be the cradle of the evolution of humans. The Depression overlaps the borders of Eritrea, Djibouti and the entire Afar Region of Ethiopia; and it contains the lowest point in Africa, Lake Assal, Djibouti, at below sea level. The Awash River is the main waterflow into the region, but it runs dry during the annual dry season, and ends as a chain of saline lakes. The northern part of the Afar Depression is also known as the Danakil Depression. The lowlands are affected by heat, drought, and minimal air circulation, and contain the hottest places (year-round average temperatures) of anywhere on Earth. The Afar Triangle is bordered as follows (see the topogr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Assal (Djibouti)
Lake Assal ( ar, بحيرة عسل , lit. “Honey Lake”) is a crater lake in central-western Djibouti. It is located at the western end of Gulf of Tadjoura between Arta Region, and Tadjoura Region, touching Dikhil Region, at the top of the Great Rift Valley, some west of Djibouti city. Lake Assal is a saline lake that lies below sea level in the Afar Triangle, making it the lowest point on land in Africa and the third-lowest point on Earth after the Sea of Galilee and the Dead Sea. No outflow occurs from the lake, and due to high evaporation, the salinity level of its waters is 10 times that of the sea, making it the third most saline body of water in the world behind Don Juan Pond and Gaet'ale Pond. The salt in the lake is exploited under four concessions awarded in 2002 at the southeast end of the lake; the major share of production (nearly 80%) is held by Société d’Exploitation du Lac and Société d’Exploitation du Salt Investment S.A de Djibouti. The lake is a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Karum
Lake Karum (also known as Lake Assale or Asale) is a salt lake in the Afar Region of Ethiopia. One of two salt lakes in the northern end of the Danakil Depression (the other one being Lake Afrera), it lies at -120m (-394ft) relative to sea level. The volcano Erta Ale rises southeast of this lake. Werner Munzinger, who traveled through the Afar Depression in 1867, recorded that this lake was fed by four streams: The Didic, the Ala, the Rira Guddy, and the Ragali or Awra, which is the only permanent stream flowing into Lake Karum.Munzinger"Narrative of a Journey through the Afar Country", ''Journal of the Royal Geographical Society'' 39 (1869), p. 204 North of Lake Karum is the former mining-settlement of Dallol. The lake is extremely salty and is surrounded by a salt-pan, which is still mined. The salt is transported by caravan to the rest of the country.

Bathymetric
Bathymetry (; ) is the study of underwater depth of ocean floors (''seabed topography''), lake floors, or river floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography. The first recorded evidence of water depth measurements are from Ancient Egypt over 3000 years ago. Bathymetric (or hydrographic) charts are typically produced to support safety of surface or sub-surface navigation, and usually show seafloor relief or terrain as contour lines (called depth contours or isobaths) and selected depths ('' soundings''), and typically also provide surface navigational information. Bathymetric maps (a more general term where navigational safety is not a concern) may also use a Digital Terrain Model and artificial illumination techniques to illustrate the depths being portrayed. The global bathymetry is sometimes combined with topography data to yield a global relief model. Paleobathymetry is the study of past underwater depths. Seabed topography ...

Sulfuric Acid
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid ( Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula . It is a colorless, odorless and viscous liquid that is miscible with water. Pure sulfuric acid does not exist naturally on Earth due to its strong affinity to water vapor; it is hygroscopic and readily absorbs water vapor from the air. Concentrated sulfuric acid is highly corrosive towards other materials, from rocks to metals, since it is an oxidant with powerful dehydrating properties. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid, but to the contrary dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is released; thus the reverse procedure of adding water to the acid should not be performed since the heat released may boi ...

2011 Nabro Eruption
The 2011 Nabro eruption was an eruption of the Nabro stratovolcano in the Southern Red Sea Region of Eritrea, which began on 12 June 2011 after a series of earthquakes. The eruption killed seven and possibly a further 31 people and is estimated to be the highest altitude injection of sulfur dioxide (SO2) ever observed by satellite. The Mount Pinatubo eruption 20 years earlier emitted ten times more SO2. The ash cloud from the eruption reached altitudes which disrupted airline traffic in the region. Until the eruption began, the volcano had no records of historical eruptions.

Brine
Brine is a high-concentration solution of salt (NaCl) in water (H2O). In diverse contexts, ''brine'' may refer to the salt solutions ranging from about 3.5% (a typical concentration of seawater, on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature). Brine forms naturally due to evaporation of ground saline water but it is also generated in the mining of sodium chloride. Brine is used for food processing and cooking (pickling and brining), for de-icing of roads and other structures, and in a number of technological processes. It is also a by-product of many industrial processes, such as desalination, so it requires wastewater treatment for proper disposal or further utilization (fresh water recovery). In nature Brines are produced in multiple ways in nature. Modification of seawater via evaporation results in the concentration of salts in the residual fluid, a characteristic geologic deposit call ...

Ethiopian Mineral Resources Development Enterprise
Ethiopians are the native inhabitants of Ethiopia, as well as the global diaspora of Ethiopia. Ethiopians constitute several component ethnic groups, many of which are closely related to ethnic groups in neighboring Eritrea and other parts of the Horn of Africa. The first documented use of the name "Ethiopia" from Greek name "Αἰθίοψ" (Ethiopian) was in the 4th century during the reign of Aksumite king Ezana. There were three ethnolinguistic groups in the Kingdom of Aksum; Semitic, Cushitic, and Nilo-Saharan (ancestors of the modern-day Kunama and Nara). The Kingdom of Aksum remained a geopolitically influential entity until the pillage of its capital — also named Axum — in the 10th century by Queen Gudit. Nevertheless, the core Aksumite civilization was preserved and continued into the successive Zagwe dynasty. By this time, new ethnic groups emerged – the Tigrayans and Amharas. During the Solomonic period, the latter established major political and cult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
