I-United States Geological Survey (USGS) usanda kushicilela ibalazwe elibonisa ukukhubazeka okwenzeka phansi. Ukukhubazeka kwenzeke ngemuva kwengcindezi ebangelwe ukuzamazama komhlaba komhlaba eminyakeni emibili edlule. Indawo ezungeze le caldera volcanic, okuyiyona ngempela le ntaba-mlilo, ibhekane nokuzamazama okungu-1500 kobukhulu obuhlukile ezinyangeni ezimbili ezedlule kuphela.
Isizathu sokuthi iyi-caldera, futhi hhayi kahle intaba eyodwa, ukumelwa kobukhulu bamandla ayo. I-supervolcano inamandla kangangokuba yonke intaba ngokwayo iyabhidlika futhi izibhidlize ngokwayo. Ngokulandelayo, ukwakha iphuzu lokuqhuma, kukhulu kakhulu kunokujwayelekile.
Imininingwane yobuchwepheshe emayelana nokuzamazama komhlaba kwase-Yellowstone
Selokhu kwaqala ukuzamazama komhlaba ngoJuni 12, sekuqoshwe ukuzamazama okungaphezu kuka-1500. Ukudlidlizela kwaseYellowstone kubhalwe phansi kusuka endaweni efanayo kuya ku-14 km ukujula. Ubukhulu obukhulu oburekhodiwe bungu-5 esikalini sikaRichter.
Ingozi enkulu ye-Yellowstone iza ngaphezu kwakho konke kusuka emiphumeleni engaba nayo ukuqhuma kwayo. Imiphumela ukuqhuma kwe-supervolcano okungaba nayo, kungalingana nezintaba-mlilo ezijwayelekile ezingaba yikhulu. Kuphinde kwafundwa ukuthi imiphumela lokhu kuqhuma okube nayo kuwo wonke amarekhodi e-paleontological, kungaguqula nesimo sezulu. Yize yonke intaba-mlilo ibhekwe ngeso lokhozi, kuyiqiniso ukuthi ososayensi abazi kahle ukuthi bangabikezela kanjani ukuthi bangavuka nini. Muva nje enye i-supervolcano ekhombisa izimpawu zomsebenzi owandayo yile ICampi Flegrei, e-Italy, okuqapha kwakhe kugadwa kakhulu.
Ukuqhuma kwazo zombili izintaba-mlilo kuzoba nemiphumela ezigidini zabantu abahlala eduze kwabo. Ngaphandle kwalokhu, okwamanje kufanele kuqashelwe ukuthi ukuqhuma akunakwenzeka. Yebo, ezikhathini eziningi, yize zandulelwa ngomsebenzi, umsebenzi awuhambisani ngaso sonke isikhathi nokuqhuma.
