Ukusuka ekhephini ukunqumla kuluhlu olubanzi lweendawo ezingonakaliswanga, ikhephu elingazani nantombi ukuya kuphonononga intlango eyahlukeneyo, okanye ukunyuka intaba kumhlaba weqhwa oneminyaka eli-125.000 ubudala.
Inyani yile yokuba esi siqithi sinika amava angenakulibaleka angenakulibaleka msinyane. Isiqithi siyamangalisa ngenxa yezizathu ezininzi.
