KwiNtaba iAgung uyakufumana Intaba-mlilo yaseBali kwaye isengozini yokuqhuma okukhulu. Imifanekiso yayo ithathiwe kwaye babenakho nokuchaza imbali yento eyenzeka ngaphakathi.
Ngaba uyafuna ukwazi ngakumbi ngeBali volcano kunye nembali yayo?
Intaba-mlilo yaseBali
INtaba iAgung iye yahlangabezana namava inyikima ephezulu kwezi nyanga zimbini zidlulileyo. Nangona kungenjalo ngendlela emiselwe kwangaphambili, ukwanda kwenyikima kummandla wentaba-mlilo kuyahambelana nokuqhuma kwayo. Ifumene ukuqhekeka okukhulu kwamatye ngaphakathi kwintaba-mlilo eyakha yabonwa, ukusukela oko umagma, engumxube otyibilikisayo wamatye anyibilikileyo, ulwelo kunye neegesi, ebesuka ezinzulwini zomhlaba ukuya phezulu kancinci kancinci, ukuqhekeka kweendonga.
Kwezi veki zidlulileyo kuye kwenzeka ukuqaphela iziqwenga ezityebileyo zomphunga kunye nothuthu inyuka phezulu kwintaba-mlilo kunye nentaba-mlilo kumphezulu womngxuma. Ukongeza, kufunyenwe imilambo emincinci yodaka olubandayo oluhamba ngeentili.
Kwiifoto zokuqala ezithathwe kwiinyanga ezimbalwa ezidlulileyo, akukho mntu wayenokuqinisekisa ukuba i-volcano yayilungiselelwe ukuqhuma. Nangona kunjalo, ukwanda kwenyikima nokushukuma komhlaba okushukumise indawo, yayilumkisa abantu malunga nolu dubulo lusemnyango.
Iimpawu zentaba-mlilo
Eyona nto iye yaqatshelwa kule volcano kukonyuka komphunga kubangelwa, ngokulula, ngamanzi ngaphakathi kwentaba-mlilo afudumeza anyukele phezulu. Umxube wentaba nothuthu lwentaba-mlilo ufana nesiponji, kwaye kwiIndonesia enethayo, amanzi ayafunxa aze ahlale apho de afudumale.
Ukusukela ngoko, intaba-mlilo yahlala izolile kwaye izinzile de, ngolwe-Lwesibini, intaba-mlilo yaqala ukukhupha uthuthu kunye nomphunga, ukuqala ukuqhuma ngaphezulu kweminyaka engama-50. Oku bekukho ukuqhuma kwe-phreatic. Oko kukuthi, ukugxothwa komphunga oxinzelelweyo ukusuka ngaphakathi kwintaba-mlilo kuba umagma ongaphakathi kuyo ufudumeza amanzi. Oku kungakhokelela ekwandeni koxinzelelo olwenza ukuba kuqhushumbe kuqhushumbe ilitye kunye neziqwengana zomngxunya wentlabathi zibe lucwecwana lomlotha.
Imagma ibisuka ngaphakathi kwaye iqhekeza amatye njengoko iqhubeka. Amanzi ngaphakathi kwentaba-mlilo ayatshisa kwaye ashushu, abangele ukuba umphunga wamanzi unyuke kuxinzelelo, ufike kwinqanaba apho iliwa ayisenakuyibamba kwakhona kwaye iyaqhekeka. Yile nto siyibonayo ngoku. I-magma ihambele phezulu kakhulu kwi-volcano kangangokuba bekungekho liwa laneleyo lokuyigcina, ke iyajika ibe ngamaqhekeza omlotha kwaye isasazeka.
Ukufundwa kwemeko yentaba-mlilo
Impendulo ye-volcano iyafundwa kunye nendlela eya kuguquka ngayo. Ukwenza oku, kujongwa iimpawu zeentsika zogqabhuko-dubulo okanye iiplamu zothuthu. Ukuba ezi ziyenyuka ngaphandle komoya, oko kuthetha ukuba isantya sazo siphezulu. Kwintaba-mlilo, isixa sothuthu kunye nesantya esiphuma ngaso sigqiba ukuba iplume inokuthi ihambe phezulu kangakanani kwaye ke ngaloo ndlela ikwazi ukuvavanya umonakalo onokubakho xa kufikelela kuloo ntaba-mlilo.
Ekudubuleni kweNtaba iAgung ngo-1963, Ukuqhuma kufikelele kwi-26 km (Iikhilomitha ezili-16) ngaphezulu komphakamo wolwandle. Kwiintaba-mlilo ezinje ngeAgung, imagma inokuhamba i-5-15 km ukuya kumphezulu ukusuka kubunzulu bomhlaba, ekhokelela kuqhushumbo.
Esinye sezizathu zokuba abasemagunyeni baphakamise inqanaba lokulumkisa ukuya kwesine kungenxa yokuba umagma uya esiba phezulu. Imifanekiso yamva nje evela e-Bali yalatha kuphuhliso olutsha, oludaka lwentaba-mlilo, okanye i-lahars. Uthuthu kunye namatye ahlala ajikeleze intaba-mlilo xa edityaniswe nemvula angadala imilambo ehamba ngokukhawuleza eyingozi ukungaguquguquki kwamanzi kwikhonkrithi emanzi, kwaye enokuhamba kunye nokutsala.
