Italian authorities have closed roads and evacuated mountain huts after experts warned that part of a glacier on Mont Blanc could collapse.
About 250,000 cubic metres of ice are in danger of breaking away from the Planpincieux glacier on the Grandes Jorasses peak.
The Mont Blanc massif is Western Europe’s highest mountain range. It has 11 peaks above 4,000m in France and Italy and attracts hundreds of thousands of tourists every year.
On Tuesday, Courmayeur Mayor Stefano Miserocchi signed an order closing roads in the Val Ferret on the Italian side of Mont Blanc, after experts warned that a section of the glacier was sliding at speeds of 50-60cm (16-23in) per day.
He said there was no threat to residential areas or tourist facilities but mountain huts in the Rochefort area were being evacuated as a precaution.
Experts from the Valle d’Aosta regional government and the Fondazione Montagna Sicura (Safe Mountain Foundation) say it is impossible to predict exactly when the mass of ice will collapse.
The Planpincieux glacier has been closely monitored since 2013 in an attempt to establish the frequency with which ice is melting. But authorities warn that there is no “alert system” in place.
In one weather-related incident in August 2018, an elderly couple were killed near Planpincieux in Courmayeur when their car was swept from a road and into a valley during a landslide. Hundreds of people were evacuated, some of them by helicopter.
Earlier this month, dozens of people took part in a “funeral march” to mark the disappearance of the Pizol glacier in north-east Switzerland.
Last month, a ceremony took place in Iceland to commemorate a glacier that was officially declared dead five years ago.
About 2 months ago, a mysterious lake suddenly appeared near the top of the Mont Blanc – one that admittedly is not usually there.
While some glaciers disappear, other increase their ice masses. We are in a real climate chaos. [BBC]
