Afar Danakil Depression
Among Africa's most eye-catching geographical features is a huge tear across the planet's surface noticeable even from the sky - the Great Rift Valley. Stretching out from the Middle East up to Mozambique, this Rift Valley goes by in a northeasterly to Southwestern direction through Ethiopia, bestowing the country with a number of breathtaking sights consist of hot, dry, plus barren areas to a series of gorgeous lakes. This great collapse on the earth's surface took place concurrently which the Arabia Peninsula - geologically part of Africa. This Afar Depression is a platter tectonic triple junction in which the spreading side rails that form the Red Sea plus the Gulf of Aden come out on land and finally meet the great East African Rift. This Afar Depression is one of the two places on the planet in which a mid-ocean ridge may be studied here on land and the other being found Iceland. Currently, the Afar is gradually being ripped apart at a rate of 1 to 2 cm each year. The bottom of the Afar Depression consists mainly of basaltic lava. This Afar Depression as well as the Triple Junction as well marks the place of a mantle plume, an outstanding uprising of mantle which melts to form basalt.
This area which was once a section of the Red Sea has several miles of salt deposits. In certain areas the slat deposits are approximately Three miles (five kilometers) thick. Beneath a salt lake is a significant source of volcanic-heat which in turn causes leads to hot water rising through the salt layers and anhydrite deposits. The Minerals are dissolved and then deposited close to the springs to form shapes greatly similar (however smaller compared to) hornitos on the basaltic lava flows. In addition, Sulphur plus other minerals and perhaps Thermopylae bacteria cause breathtaking colors, Sundered from the remainder of the continent. Within Eastern Ethiopia, close to the southern extreme of the Red Sea, an enormous, pretty much triangular depression goes down far below the sea level (at some places 120m below sea level). Referred to as Danakil Depression, this very hot as well as arid area is in reality a section of the Africa's Rift Valley. In this apparently unfriendly area there are the nomadic Afar people that are about Three million in number. Their outside borders are Somalia, Eritrea plus Djibouti. The area where these people stay is as well referred to as Afar one of the 9 regions of this country. Its current capital is known as Semera on the smoothed Awash - Assab highway. Danakil, or Dallol depression, that features a great part of the eastern section of the Tigray region, is among the earth's hottest as well as most unfriendly places, with several points over 100m (or 328 feet) below sea level and the mid-day temperatures can rise as high as over 50 degrees Celsius (or 122 degree Fahrenheit)
It's the place of a dry out salt lake in which Ethiopians for hundreds of years have acquired their amoles (bars of salt) used for consumption and, in the past, as an old fashioned form of money. The Afar people not less than a millennium have minded salt here and loaded it on camels and then taken it to the highlands together with extended caravans, where it's still in substantial demand and brings a good price tag.
A unique place referred to as "Erta Ale" (among the most significant active volcano on the planet) is situated in the Afar depression (13.6°N, 40.67°E) at an altitude of 613m. This is a shield volcano that has a base diameter of 140 meters; 60 - 90 meters deep presently has an active lava-lake which is 100 meters long and 60 meters wide.
