Great Rift Valley

Ikibaya kinini cya Rift ni izina ryatanzwe muri 1894 n'umushakashatsi ukomoka muri ekosi witwa John Walter Gregory, nyuma y'urugendo rwe muri Afurika y'Iburasirazuba , mu itsinda ryari irya geologiya rigizwe n'uruhererekane rw'ibishanga n'ibirunga, biherereye muri Afurika y'Iburasirazuba .

ryitwa irya furika y'Iburasirazuba cyangwa "Irikora kuri afurika y'Iburasirazuba", iri rigizwe n'amashami menshi agabanijwemo ibice by'ibibaya, nayo ubwayo agabanijwemo uduce duto, ikibaya cy'amasoko. Ibi byinjira mu imiterere yose izina rya sisitemu yo muri Afrika yuburasirazuba . Ihuriro hamwe n’’inyanja Itukura, Ikigobe cya Suez Ikosa na Levant Fault bigize Sisitemu ya Afro-Arabiya.

Mubyukuri, amakosa yose ya tectonic yerekeje muri Afrika no muri Aziya Ntoya nko mu kilometero cya  7 000, uva mu majyaruguru ugana mu majyepfo, na kilometero  30 Kuri kimometero 100 z'ubugari, kuva muri Libani kugera muri Mozambike, unyura ku nyanja Itukura n'ibiyaga binini byo muri Afurika  . Igabanya Ihembe rya Afurika mo kabiri: isahani ya Somaliya, iburasirazuba, iragenda iva ku isahani ya Afurika, y'iburengerazuba. Igabanyijemo, igana mu majyepfo ya Etiyopiya, ku mpande zombi za Uganda . igashamika  iry’iburengerazuba ( Albertine rift ) rinyura mu biyaga binini byo muri Afurika, ryakozwe no kwegeranya amazi mu kwiheba, mu gihe ishami ry’iburasirazuba ( Gregory rift ) ryambukiranya Kenya na Tanzaniya mu burasirazuba bw’ikiyaga cya Victoriya, aho rigizwe n'umugozi muto.

 Ubumenyi bwa geologiya 

 Kumeneka 
Kuva mu majyaruguru ugana mu majyepfo, tectonike agizwe no yo kwa Afar (harimo Ikigobe cya Tadjoura na Block ya Danakil ), ikibaya cya Awash, ikibaya cya Omo, ikiyaga cya Turkana, nyuma y’ikosa rya Afurika ryigabanyijemo amashami abiri, rigira Ikomeye Ibiyaga bya Afurika mu burengerazuba n'ibiyaga bito mu burasirazuba bw'ikiyaga cya Victoria, kugira ngo bihure mu majyepfo mu kiyaga cya Malawi no mu kibaya cya Shire, mu majyepfo ya Malawi .
