Ukuqhubeka ne-Yellowstone, kulinganiselwa ukuthi lesi simangaliso semvelo esimangalisayo saqhuma okokugcina cishe eminyakeni eyizinkulungwane ezingama-640 edlule, izinkulungwane ezingama-640 !! Akuyona inombolo emangalisayo leyo? Futhi uma leli qiniso limangalisa, likwazi kakhulu lokho ukuqhuma okukhulu okudala kunakho konke bekuyiminyaka eyizigidi ezimbili edlule. Akunalutho!

Kepha… thina sikubiza ngokuthi i-supervolcano? Lezi yizintaba-mlilo ezinekamelo lamagma elikhudlwana izikhathi eziyizinkulungwane kunezinga elijwayelekile ngaphansi koqweqwe lwawo.Okusho ukuthi, uma ivuka, izokwenza ngodlame olukhulu kakhulu, ithumele izinkulungwane zamakhilomitha angama-cubic of matter emkhathini.

Njengoba sishilo, noma kunenqwaba, akulindelekile akukho ukuqubuka okukhulu.

Ucabangani? Ubuwazi lawa amanye ama-supervolcanoes?
