Ugqabhuko-dubulo lwentaba-mlilo yaseMauna Loa

ugqabhuko-dubulo lwentaba-mlilo i-mauna loa

Mauna loa IHawaii igqabhuka okokuqala kwisithuba esingaphezu kweminyaka engama-40. I ivolcano enkulu emhlabeni Uye wagqiba ekubeni avuke ekoneni kwakhe. I-Mauna Loa iqale ukugqabhuka phezolo kunye neentanda ezintsha ezivulekileyo phezulu kwintaba-mlilo.

Siza kukuxelela zonke iindaba malunga nogqabhuko-dubulo lwentaba-mlilo iMauna Loa.

Ugqabhuko-dubulo lwentaba-mlilo yaseMauna Loa

ukuqukuqela kwelava ukusuka eMauna loa

Ugqabhuko-dubulo olutsha lweMauna Loa lwabonwa eHawaii ngo-2:16 am. IMauna Loa iqhume ngentseni izolo isuka kweyona crater ephezulu, iMoku'āweoweo. IGiant Shield Volcano kwiSiqithi Esikhulu saseHawaii ibingasebenzi iminyaka engama-38. Olu gqabhuko-dubulo lulandele iikhonto zogqabhuko-dubulo lwendlela yaseHawaii, enentanda phezulu, imithombo yodaka, kunye nokuqukuqela kodaka oluphuma kwimingxuma emitsha.

Ngenxa yalo msebenzi mtsha, i-USGS Hawaii Volcano Observatory itshintshe isimo sesilumkiso se-Mauna Loa ukuya kwi-Red/Isilumkiso. Ngoku, akukho sisongelo kubahlali abajikeleze intaba-mlilo, njengoko ugqabhuko-dubulo lunokwenzeka ukuba luphelele encotsheni. Nangona kunjalo, ukusuka ekupheleni kwengqungquthela, i-lava iqukuqela ngokukhawuleza emhlabeni.

I-USGS ibika ukuba ukuqukuqela kwe-lava kuye kwaphalala kumzantsi-ntshona ukusuka kwi-summit crater, kodwa ugqabhuko-dubulo luseza ukusuka encotsheni. Nangona kunjalo, ukuvulwa kweeshafts ezintsha zokungenisa umoya ngaphandle kwe-summit crater akukhutshelwa ngaphandle.

Ukuqukuqela kodaka lweArctic kwenzeke macala onke eMauna Loa, abanye babo beza kwindawo ngoku ebizwa ngokuba yiHilo ngeminyaka yoo-1880. Ikwanesakhono sokuvelisa imisinga enokufikelela ukusuka eMzantsi Kona ukuya kwelinye icala lesiqithi. Ngoko ke, kukho isisongelo sokuqukuqela kodaka olunokufikelela kumzantsi-ntshona, kumntla-mpuma, nakumntla-ntshona weMauna Loa. Ngokuxhomekeke kubukhulu bogqabhuko-dubulo, inkungu yentaba-mlilo inokuba yingozi yokuphefumla.

ugqabhuko-dubulo lwembali

udaka luphuma kwintaba-mlilo yaseMauna Loa

Njengoko iimephu ze-lava zihamba ukusuka kwiminyaka engama-200 edlulileyo zibonisa, IMauna Loa yintaba-mlilo eqhuma kakhulu. Olu gqabhuko-dubulo luphantse lube yiminyaka engama-40 lunqabile kwimbali yalo yanamhlanje. Kubekho iimpawu kwiinyanga zamva nje zokuba intaba-mlilo iyagqabhuka, ngokunyuka kwentshukumo yenyikima ngaphakathi kwentaba-mlilo. Le ngqungquthela ibonakala ngathi ikhubazeke kancinane de kuqale ugqabhuko-dubulo olutsha.

Ugqabhuko-dubulo olutsha luthetha ukuba zombini iMauna Loa kunye I-Kilauea zidubula kwisiqithi esikhulu. Ukudubula kabini akunto ingaqhelekanga eHawaii, nangona bekukho amacebiso athile kwiminyaka eli-1000 XNUMX edluleyo okuba ezi ntaba-mlilo zimbini zinokutshintshana. Zombini ezi ntaba-mlilo zagqabhuka ngowe-1975 nangowe-1984, kodwa yiKilauea kuphela eye yagqabhuka ukususela phakathi kwiminyaka yee-1980.

Zombini ezi ntaba-mlilo ekugqibeleni zondliwa yindawo eshushu ephantsi kweHawaii: uloliwe wengubo eshushu onyukayo usuka ezantsi eMhlabeni, unyibilika njengoko ufikelela kumazantsi olwandle lweemayile ezisezantsi kwesiqithi. Nangona zombini iintaba-mlilo zabangelwa yile mantle plume, i-isotopic kunye ne-trace element yokwakheka kwe-lavas eqhumayo yaseMauna Loa kunye neKilauea yahluka kakhulu kangangokuba izifundo zegeology yeentaba-mlilo zaseHawaii. Izazinzulu ziyakukholelwa oko zinokuvela kwiindawo ezahlukeneyo zombhobho wengubo.

Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nogqabhuko-dubulo lwaseMauna Loa kunye neempawu zalo.
