    Tanzania



    Ol Doinyo Lengai is actually a volcano that is been located in the northern regions of Tanzania as well as is component of the renowned volcanic system that is present in the Great Rift Valley and is located in Eastern Africa. Ol Doinyo Lengai is positioned in the eastern Rift Valley, in the southern region of both the Lake Natron as well as Kenya. Moreover it is only one of its kinds amongst active volcanoes in the system that produces the natrocarbonatite lava, which is an only one of its kind happening of volcanic carbonatite. Furtherore, the temperature of the lava from Ol Doinyo Lengai as it appears is barely around 950 °F (510 °C). A small number of the older vanished carbonatite volcanoes and are located in close proximity, which includes Homa Mountain.


    In addition the meaning of “Ol Doinyo Lengai” is “Mountain of God” which is in the native language of the locally based Maasai people. Moreover the records of the eruptions that take place on this mountain dates back to the year 1883, as well as flows were in addition recorded between the years 1904 as well as 1910 and once more between the years 1913 and 1915. Moreover, a major volcanic eruption had occurred in the month of June 1917, and resulted in the volcanic ash that was being deposited in a region of 48 kms.

    An analogous eruption took place for quite a lot of months in the year 1926 as well as between the months of July and December in the year 1940, which resulted in the deposition of ash as far as the regions of Loliondo, which is a located almost100 kilometre away. Quite a lot of minor eruptions of the lava were been observed in the year 1954, and 1955, also 1958 as well as in 1960s.


    In the modern times, the volcanoes of Ol Doinyo Lengai have erupted in the year 1966, on August 14. Two geologists named J. B. Dawson as well as G. C. Clark who had visited this crater a week afterward had reported observing “a chunky column of the black ash” that might have rose for just about three thousand feet on top of this volcano in addition to drifted away in the north in the direction of Lake Natron. As soon as these two climbed the huge cone-shaped vent, they had reported observing an unremitting liberation of gas as well as whitish-grey ash along with dust that came out from the central region of this pit.


    In addition, the volcanic activity within this mountain that had caused earth tremors, on a daily basis in the regions Kenya as well as Tanzania began on July 12, 2007. Moreover the most recent for hitting parts of the Nairobi city were been recorded in the year 2007 on July 18 at 8.30pm.
