Uphando lwejoloji lwaseMelika (I-USGS) usandula ukupapasha imephu ebonisa ukungalunganga okwenzeka emhlabeni. Ukutshintsha kwenzeke emva koxinzelelo olubangelwe kukungcangcazela komhlaba ngaphantsi kweminyaka emi-2. Indawo engqonge le ntaba yentaba-mlilo, eyiyeyona ntaba-mlilo, ifumene iinyikima ezili-1500 zobukhulu obahlukeneyo kwiinyanga nje ezimbini ezidlulileyo.
Isizathu sokuba yi-caldera, kwaye hayi intaba enye, kukumelwa kobukhulu bamandla ayo. I-supervolcano yomelele kangangokuba yonke intaba ngokwayo iyawa kwaye izibhodloze ngokwayo. Emva koko senza indawo yokuqhuma, inkulu kakhulu kunokuba iqhelekileyo.
Idatha yobuchwephesha malunga neenyikima zeYellowstone
Ukusukela oko iinyikima zaqala nge-12 kaJuni, ngaphezulu kwe-1500 iinyikima ezirekhodiweyo. Iinyikima eYellowstone zirekhodwe ukusuka kumhlaba omnye ukuya kwi-14 km ubunzulu. Ubukhulu obukhulu oburekhodiweyo yayingu-5 kwisikali seRichter.
Umngcipheko omkhulu we-Yellowstone uvela ngaphezulu kwako konke ukusuka kwiziphumo zokuqhuma kwawo. Iziphumo zokuqhuma kwe-supervolcano, inokulingana ne-100 yeentaba-mlilo eziqhelekileyo. Kukhe kwafundwa kananjalo ukuba iziphumo zoku kuqhambuka ziye zaba nazo kwiirekhodi zepaleontology, zinokuguqula imozulu. Nangona zonke i-supervolcanoes zijongwa, kuyinyani ukuba izazinzulu azazi ncam ukuba zingaqikelela nini ukuba zingavuka nini. Kutshanje enye i-supervolcano ebonisa iimpawu zomsebenzi owandileyo yile ICampi Flegrei, e-Itali, ekubekweni esweni kugadwe ngakumbi.
Ukuqhuma kwazo zombini ezi mlilo kuya kuba neziphumo kwizigidi zabantu abahlala kufutshane nabo. Ngaphandle koku, okwangoku Kufuneka kuqatshelwe ukuba ukuqhuma akunakwenzeka. Ewe, kumaxesha amaninzi, nangona zilandelwa ngumsebenzi, umsebenzi awusoloko uhamba nogqabhuko-dubulo.
