Lo scivolamento a valle del villaggio grigionese di Brienz continua a rallentare, grazie ai cunicoli di drenaggio. La velocità di spostamento è attualmente compresa tra i 10 e i 25 centimetri l’anno. Un valore così basso non si vedeva da 15 anni. Lo ha comunicato venerdì il comune di Albula nel suo bollettino informativo.
Secondo il Comune, le diminuzioni sono in corso dalla metà di dicembre. Un contributo significativo a questa evoluzione positiva è stato dato dalle perforazioni di drenaggio: il flusso d’acqua nella galleria è passato da 1’500 a 800 litri al minuto.
Anche le velocità di scorrimento sulla montagna sono leggermente diminuite. Il futuro a lungo termine della popolazione di Brienz è comunque attualmente incerto e le condizioni della montagna devono essere rivalutate entro la fine di gennaio. I 90 abitanti del villaggio erano stati evacuati nel novembre 2024.
