L'allarme per la caduta di massi avvenuta giovedì mattina a Felsberg è parzialmente rientrato. I residenti delle tre case evacuate hanno potuto ritornare nelle abitazioni. Rimane transennata un'area giudicata pericolosa per gli abitanti del comune grigionese limitrofo a Coira. L'amministrazione comunale comunica che il pericolo attuale è stato giudicato sotto controllo.

La massa precipitata a valle viene stimata fra i 20'000 e i 30'000 metri cubi e nessuna persona è rimasta ferita. Soltanto la facciata di una casa ha subito danni da schegge di roccia.
Nel pomeriggio di giovedì gli esperti dell'Ufficio delle foreste e dei pericoli naturali dei Grigioni e alcuni geologi hanno ispezionato il sito dove si è staccata la frana con un con un elicottero e con un drone per valutarne il pericolo. In base alle prime rilevazioni, non ci si aspettano ulteriori grandi frane e il pericolo viene giudicato di poca entità. Tuttavia il monitoraggio della zona viene intensificato e valutato costantemente.
