La zona del ghiacciaio Trift, sopra Saas-Grund nel canton Vallese, è stata chiusa oggi, sabato, a causa di un rischio significativo di frane. Un'intera lingua del ghiacciaio, tenuta sotto osservazione dal 2014, minaccia infatti di crollare: tra i 200'000 e i 500'000 metri cubi di materiale potrebbero scendere a valle entro domenica sera, stando a quanto previsto dagli esperti.
Una cinquantina di abitazioni nella zona più a rischio del comune vallesano è stata fatta evacuare. Il resto del paese non è invece in pericolo.
L’obiettivo è che nessuno trascorra la notte nella zona considerata in pericolo, come confermato ai microfoni del Radiogiornale dal sindaco del comune vallesano, Bruno Ruppen. Sono stati mobilitati i vigili del fuoco e la protezione civile.
