'Isilumkiso esibomvu' sikhutshwe ngenqwelomoya njengoko kuqhuma intaba-mlilo enkulu yaseAlaska

• I-Ash plume evela kuqhushumbo lwentaba-mlilo iGreat Sitkin yayiphezulu nge-15,000ft (4,600m)
• Olu dubulo lwalandulelwe kukunyuka kwesiphithiphithi sentaba-mlilo kwiiyure ezingama-24 ezidlulileyo
• Intaba-mlilo iye yadubula okwexeshana nje kule minyaka ilikhulu idlulileyo

The Uphengululo lweejiyometri zase-US (USGS) ikhuphe ingxelo namhlanje ibhengeza ukuba umsebenzi wentaba-mlilo kwiSiqithi iGreat Sitkin uqinisekisiwe ngedatha ye-geophysical. I-volcano iqale ukuqhuma nge-9: 04 pm ngolwe-Lwesibini, ngoqhushumbo oluthathe imizuzu embalwa, kwaye yayiqhubeka ukuqhuma ngexesha lohlaziyo lwayo lwamva nje. 

Ukuqhuma kukhuthaze i-USGS kunye I-Alaska Volcano Observatory (AVO) ukukhupha 'isilumkiso esibomvu' ngokudibeneyo kwezokuhamba ngenqwelomoya emva kokuqwalaselwa kokucebisa ukuba uthuli lwentaba mlilo omkhulu waseSitkin lwaluphakame kangange-15,000ft (4,600m).

"Ukusukela oko kuqhuma, ukunyikima komhlaba kwehlile, kwaye imifanekiso yesathelayithi ibonisa ukuba ilifu lothu lisukile emoyeni kwaye liya ngasempuma," yatsho iAlaska Volcano Observatory kuhlaziyo lwamva nje. 

Inani leefoto kwimidiya yoluntu, ezinye zingaqinisekiswanga, zibonakala zibonisa ilifu lomlotha lixhonywe phezu kolwandle kunye neziqithi ezikude. Omnye umfanekiso (obonisiweyo), mhlawumbi othathwe kuluntu lwaseAdak, malunga neekhilomitha ezingama-26 (43km) kwintshona ye-volcano, ubalaselisa ubungakanani bokukhutshwa.

Olu dubulo lwandulelwa kukunyuka kwesiphithiphithi sentaba-mlilo kwiiyure ezingama-24 ezidlulileyo, kwaye ubushushu bomhlaba obuphakamileyo kunye nesalfure dioxide zabhaqwa kule veki iphelileyo.

IGreat Sitkin yenye yeziqithi zeAleutian, uninzi lwazo zikwilizwe laseMelika iAlaska. Intaba-mlilo, uninzi lwayo phakathi kweziQithi zeAleutian, iye yaqhushumba okwexeshana kule minyaka ingama-100 idlulileyo, okona kutsha nje kukuqhushumba okuncinci ku-2019.
