La frana che sovrasta il villaggio grigionese di Brienz continua ad essere imprevedibile e attentamente monitorata. Dopo il via libera martedì mattina ai contadini che erano stati autorizzati a svolgere durante l'intera giornata i lavori di campagna nei prati inferiori della frazione di Albula, l’autorità si è vista costretta a fare marcia indietro.
Stop ai lavori agricoli a partire da mezzogiorno di martedì
In un tweet, diffuso poco fa, viene comunicato che l’accesso alla zona è annullato e i prati devono essere liberati entro le ore 11.50.
A giustificare il contrordine è stata la maggiore attività dell’isola, l’ammasso da 2 milioni di metri cubi di roccia si muove ormai di oltre 3 metri al giorno. Spia dell’accresciuto movimento sono i sassi che rotolano verso valle con un’intensità maggiore. Previsioni sull’eventuale stacco, precisano le autorità, non sono ancora possibili. Di certo però il pericolo in queste ore è aumentato.
