Zenzeka nini izimvula ezinkulu?
Ngokuyinhloko izimvula zeqhwa zibangelwa isimo seqhwa esingazinzile. Nakuba intaba embozwe yiqhwa ingase ibonakale inendawo eyodwa, empeleni yakhiwa izingqimba eziningi zeqhwa ezivela ezivunguvungwini ezihlukahlukene, ngasinye sazo esingaba nokwakheka okuhluke kakhulu. Ngokwesibonelo, iqhwa "elomile" elivela esivunguvungwini esibanda kakhulu lingase liwele ngqo phezu kwesendlalelo esishiswe ilanga esiphenduke iqhwa. Iphuzu lapho lezi zingqimba zihlangana khona libizwa ngokuthi i-interface, futhi yilapho kungenzeka khona kakhulu ukuba ungqimba olulodwa luwele kolunye. Lesi senzakalo singase sibangele ukuqhuma kwe-avalanche. Izimo zeqhwa emthambekeni zingase zishintshe ngokuhamba kwesikhathi ngenxa yomoya nelanga nezinye izimo zezulu, ngakho ngisho nomthambeka owake waba ophephile ungase ube sengozini ngaphansi kwezimo ezithile. Abantu abazilibazisa ngaphandle ebusika bangazuza ngokufunda ngalezi zimo kochwepheshe bama-avalanche.
