Kwabaninzi, zezona zisongelo ziphambili eluntwini, nangaphambi kotshintsho lwemozulu. Kwaye kukuba amandla ayo entshabalalo anokuthi aphelise ... yonke into, kwisithuba seentsuku ezimbalwa. Kodwa ungakhathazeki: nangona kukho malunga namashumi amabini eMhlabeni, ngalo mzuzu akukho namnye ofanele asixhalabise, nokuba yeyiphi edume kunayo yonke, le yaziwa ngegama nguYellowstone.
Makhe sithethe kancinci ngayo iimvulophu zehlabathi.
I-Supervolcanoes bezisoloko zinomdla kakhulu kum, kodwa hayi ngenxa yamandla abanokuba nawo, kodwa ngenxa yokuba badala kangakanani. Ukuqhubekeka neYellowstone, kuqikelelwa ukuba lo mmangaliso wendalo ungakholelekiyo ugqityelwe okokugqibela malunga nama-640 amawaka eminyaka eyadlulayo, amawaka angama-640 !! Ayililo inani elothusayo elo? Kwaye ukuba le nto iyamangalisa, ngakumbi ukwazi oko Olona dubulo ludala lwadala ukuba yiminyaka ezi-2 ezigidi eyadlulayo. Akukho nto!
Kodwa ... yintoni esiyibiza ngokuba yi-supervolcano? Ezi ziintaba-mlilo ezinegumbi le-magma ngamawaka amatyeli amakhulu kunesiqhelo phantsi koqweqwe., Oko kuthetha ukuba ukuba iyavuka, iyakwenza ngobundlongondlongo, ithumele amawaka eekhilomitha zembumba yento emoyeni. Zonke ezo zinto ziya kuba kukutshintsha imeko-bume ejikelezileyo, ukongeza kwimozulu. Ngapha koko, uqhushumbo lwakutsha nje lweYellowstone kukholelwa ekubeni lunoxanduva lokugqibela kwi-Ice Age.
Ukongeza kwiYellowstone, kukho ezinye iintaba-mlilo eMelika kwaye zikwiindawo ezahlukeneyo zehlabathi, ezinje:
- Ichibi leToba (iSumatra)
- Ummandla wentaba-mlilo iTaupo (eNew Zealand)
- ICaldera Garita (eColorado, e-USA)
- ICaldera de La Pacana (eChile)
- ICaldera Aira (eJapan)
Njengoko besitshilo, nangona zininzi, ayilindelwanga akukho rash enkulu.
Ucinga ntoni? Ngaba uyazi malunga nezinye i-supervolcanoes?
