Una frana d'importanti dimensioni s'è staccata venerdì dalla Punta Pousset, sopra Cogne, nel massiccio del Gran Paradiso. La massa di detriti ha risparmiato gli abitati e le vie di comunicazione, ma ha provocato un'imponente nuvola di polvere che ha raggiunto alcune frazioni del villaggio valdostano.
Un primo crollo s'è verificato alle 12.17 e un secondo 26 minuti più tardi. In tutto, si tratta di alcune migliaia di metri cubi di materiale, precipitate per centinaia di metri.
