Mu mfuruka ya kure y’isi, muri Antarctica, hari ahantu hatangaje hiswe Mount Erebus, umusozi w’umuriro udahoraho, utaravumbuwe n’abantu benshi. Ni umusozi w’ibirunga utandukanye n’ahandi hose ku isi, kuko ukora umuriro uhoraho mu buryo bukomeje, gutuma ugira umwihariko utagira uko usa.
Mount Erebus ni wo musozi wa karindwi ukomeye cyane muri Antarctica, kandi wihariye kubera ikiyaga cy’amazi abira kiva mu kirere cy’ubuhehere cya lava (amazi y’umuriro) yanduye cyane, bikora ahantu hashobora gutera ubwoba n’amatsiko ku bahasura benshi.

Mu gihe cy’ubushyuhe, lava yegerana ikerekana ubuzima burimo ubushyuhe butandukanye mu guhinduranya igihe.
Muri Mount Erebus, hariho uburyo bw’ibirunga bitandukanye byavumbuwe:
Amazi yo kurinda imiterere y’ibirunga bizanwa ku mpera za lava n’inyuguti.Amazi abira azana umwuka mwiza unyura ubuzima bw’abakurikirana imibereho ya lava.Ubushakashatsi bwa Antarctica bukora mu buryo butandukanye muri Mount Erebus aho harimo gukorana n’abaganga bafite imikorere ikomeye.
