Ngezikhathi zonke, izintaba-mlilo zafaka ukwesaba kwangempela kubantu, kodwa kunezindawo eziningi lapho izakhamuzi zendawo ziphoqeleka ukuba zihlangane nalezi zimpi ezinkulu. Kusukela kulesi sihloko uzofunda ukuthi yiziphi izintaba-mlilo ezinkulu kunazo zonke eMelika.
ENyakatho Melika
Kule ngxenye yezwekazi yi-volcano, okuyinto enkulu kakhulu emhlabeni , hhayi nje eNyakatho Melika. Kuthe mayelana ne-Yellowstone caldera - intaba-mlilo ephakeme, e-Wyoming, e-National Park. Ukuphakama kwalo kungamamitha ayi-2805. Ihlanganisa indawo yamakhilomitha angu-3 960, okuyingxenye yesithathu yendawo yeNational Park. Le ndawo isendaweni eshisayo, lapho ukunyakaza kwedwala elibunjiwe lesigqoko kuqondiswa khona emhlabeni. Namuhla leli phuzu limbozwe yi-Yellowstone plateau, kodwa eminyakeni eminingi eyedlule yilokho okwenza ukuba kwakhiwe ingxenye engasempumalanga yezinhlanzi zaseNyoka emva kokuqhuma okukhulu kwe-volcano.
Ososayensi bathole izinsalela zomcibisholo walo mlilo omkhulu onyakeni we-1960, oqondiswa idatha evela emfanekisweni we-satellite. Kwakukhona ukuthi isendlalelo esingaphansi kwesigcawu sisekhona ibhola elikhulu le-incandescent magma emathunjini alo. Ukushisa kulo kuhluka ngaphakathi kwamazinga angu-800. Yingakho kusukela ngaphakathi komhlaba kuya emanzini omhlaba ophunyukayo, futhi iziphethu ezishisayo zifudumala, kukhishwa i-carbon dioxide namafu e-hydrogen sulfide.

Ngokusho kososayensi, ukuqhuma kokuqala kwesiqhingi saseJ yellowstone kwenzeka eminyakeni engaphezu kwezigidi ezimbili ezedlule. Lokhu kwaholela ekuqhekekeni kwezintaba, okuhlanganisa 25% yensimu yeNyakatho Melika yanamanje ngezingqimba zomlotha oshayayo. Ukuqhuma kwesibili kubuyela eminyakeni eyizigidi ezingu-1.27 ngaphambi kwesikhathi sethu, kanti okwesithathu kwenzeka eminyakeni engu-640,000 edlule. Khona-ke kwakhiwa isakhiwo esikhulu esingenalutho engamakhilomitha angu-150, okuthiwa yi-caldera. Lokhu kwenzeka njengomphumela wokuhluleka kwe-vertex ye-volcano enkulu. Ngokusho kososayensi, kungenzeka ukuthi i-volcano enamandla ingavuka i-0.00014%. Amathuba awunaki, kodwa ukhona.
ENingizimu Melika
ENingizimu Melika, i-volcano enkulu kunayo yonke i-Cotopaxi, okuphakama kwayo kuyi-5896 amamitha. Indawo yesibili ingokwesaba se-Sangay (amamitha angu-5,410), kanti okwesithathu ku-Popocatepetel yaseMexico (ngamamitha angu-5452). Incwadi yeGuinness of Records ithi intaba-mlilo ephakeme kunazo zonke i-Ochos del Salado, engasemngceleni wase-Argentina-eChilean, kodwa kubhekwa njengokuqothulwa. Ephelele, eNingizimu Melika kunezintaba ezingu-194 ezinkulu nezincane, eziningi zazo ezingapheli.
