After three days of very heavy rain, an enormous collapse
involved the moraine of Southern Mulinet
glacier. In the upper, small valley
of Bramafam
stream (2525 m) a great incision formed in the moraine, 450 m long, till 200 m
wide and 40-50 m deep. A 200 m tract of the right morain
collapsed too. The huge mass of debris, rocks and water (800.000 m3) propagated
along Bramafam stream, and then along Gura stream, reaching the plain of Gias
Gaby huts, flooding it. The debris flow severely damaged also the village of FornoAlpiGraie: SturadiValgranderiver changed its stream, streets and meadows were covered
by debris till 4-5 m thick; road, aqueduct and sewages were swept away. The
debris-flow stopped just below FornoAlpiGraie, 4.5 km far from its
beginning.
