Ukuba utyelele ii-volcano ezinkulu emhlabeni zivakala ziyingozi, cinga kwakhona: ayizizo zonke iintaba-mlilo eziqhuma ngokuyeka kwaye zishiya iidolophu zigutyungelwe ludaka olunyibilikisiweyo nothuthu.

Nangona ngokuqinisekileyo kuyinyani ukuba iintaba-mlilo, njengeNtaba iTambora e-Indonesia (kwirekhodi njengeyona ibulala kakhulu emhlabeni) kunye neNtaba iVesuvius e-Italiya (yenye yezona ndawo zisebenza kakhulu ehlabathini), ngokwenene zibeka izoyikiso, iintaba-mlilo ezininzi azikho kangako. Injalo iMauna Loa yaseHawaii, eyenzeka njengeyona ntaba-mlilo inkulu ehlabathini, ngokomthamo nangobungakanani.

Intloko eya eHawaii

Mauna Loa ibekwe phezu Isiqithi saseHawaii , Esona siqithi sikhulu kwiziqithi ngokwaso-ligama elithetha intaba ende eHawaii. Kunye nezinye ezine zentaba-mlilo, yenza kanye esi siqithi. I-Mauna Loa ithathwa njenge-volcano ekhuselayo, ethetha ukuba yenziwe kukuhamba kwe-lava ngokuhamba kwexesha. Ezi ntaba-mlilo azide zide (ubuncinci kwihlabathi leentaba-mlilo). Endaweni yokuba bakhule bethanda ikhaka (kungoko igama). Xa ilinganiswa, iMauna Loa & apos; s lava tallies ngaphezulu kwama-56,000 iinyawo, nangona ukuphakama kwayo kungama-13,679 iinyawo kuphela.

Kucetyiswa ukuba isiqithi saseHawaii (okanye iSiqithi Esikhulu, njengoko ngamanye amaxesha sibizwa njalo) sithathe phantse isigidi seminyaka ukwenza. Kwaqala xa iintaba-mlilo ezintlanu zesiqithi zadubula kumgangatho wolwandle. Iingcali zeJoloji ziqikelela ukuba iMauna Loa ibidubula kangangeminyaka engama-700,000 kwaye yantloko yayo ngaphezu kwamanzi kwiminyaka engama-400 000 eyadlulayo. Namhlanje, iMauna Loa iyaqhubeka nokugxotha udaka, kungoko yongeza indawo yesiqithi esandayo.

Idibeneyo: Yonke into ofuna ukuyifumana malunga nendlela ezenziwe ngayo i-Volcanoes

Musa ukukhathazeka malunga nokuqhuma

Kodwa kunokuthiwani ngokuqhushumba kweMauna Loa? Kulula kakhulu, iMauna Loa ayinazo. Kuthathwa njenge-volcano engaqhushumbisi ngenxa yomxholo we-silica ophantsi kwelava yayo, iMauna Loa ineziqhushumbisi ezinamandla kakhulu. Abemi baseHawaii bebekhona kwesi siqithi malunga neminyaka eli-1,500, kodwa bashiye irekhodi elincinci lomsebenzi wentaba-mlilo eMauna Loa. Olu dubulo lwakugqibela ngo-1984, xa udaka lwentaba-mlilo lwaphuma kule ngqungquthela luye ezantsi lwaya eHilo, esona sixeko sikhulu sesi siqithi. Ilava yaphoswa yimida yesixeko malunga neekhilomitha ezine, kodwa yayiqaqambe kangangokuba ikhanyise isixeko ebusuku. Ukusukela ngoko, iMauna Loa ibithule cwaka, nangona iingcali zibanga ukubona imiqondiso enokuvuka kungekudala.

Tyelela iPaki yeSizwe

Kude kube lelo xesha, iMoana Loa yindawo ethandwa kakhulu ngabakhenkethi, itsala malunga nezigidi ezibini zabakhenkethi minyaka le ukuya eHawaii naseApos. Yiza apha uhambe ngeetyhubhu zodaka, ukonwabele ngaphezulu kweekhilomitha ezili-150 zeendlela zokuhamba, kwaye ubukele ukuqhuma kwentaba Ayisiyo iMoana Loa ethi yenze ugqabhuko, ewe -yintaba-mlilo engummelwane, iKilauea, ethi ngoku iqhume kwiindawo ezimbini.

IMauna Loa ikwahlulahlula ukuba yinxalenye yeklabhu ye-volcano, yeentlobo. I-International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI) yayiquka iMauna Loa kwiqela leentaba-mlilo ezilishumi elinesithandathu, ezaziwa ngokuba zii-Volade zeShumi. Ezi ntaba-mlilo zinomdla okhethekileyo ngenxa yomibini imigangatho ephezulu yokusebenza kunye nokusondela kumaziko amakhulu abantu. IMount Rainier yaseWashington kunye neNtaba i-Etna yaseSicily nazo zenze uluhlu.

Kodwa mhlawumbi okunomdla kakhulu, iMauna Loa inokhuphiswano lwesithsaba seyona ntaba-mlilo inkulu. Oko kukuthi, kumhlaba & umphezulu. Malunga ne-1 000 leekhilomitha kwimpuma yeJapan kukho intaba-mlilo engasekho ebizwa ngokuba yiTamu Massif — ephantsi kwamanzi. Ukufunyanwa kwayo kwabhengezwa kutshanje ngo-2013. Kwaye eyona inde? Ummelwane waseMauna Kea, intaba-mlilo eleleyo kwisiqithi esikhulu esime nje kangangeemitha ezimbalwa ukuphakama ( egqitha i-Everest ngemayile , ukuba ucinga ukuba ingakanani intaba-mlilo egxunyekwe ngaphantsi komphakamo wolwandle).

Xa kuziwa kwiintaba-mlilo, ubungakanani abukho kwaye azibalulekanga kangako njengobushushu babo.
