About 250,000 cubic meters of ice are at risk of breaking away from the Planpincieux glacier at the top of the Grandes Jorasses mountain. A section of the glacier is currently sliding off the mountain side, moving about 50-60 centimeters a day, the BBC reports, citing experts.

As a precaution, the City of Courmayeur's Mayor, Stefano Miserocchi, signed an order allowing the roads to be closed in Val Farret on the Italian side of Mont Blanc.

- These phenomena again show that the rock is in a period of change due to climate factors and especially exposed, he tells Italian media.

Attract hundreds of thousands of tourists

The Mont Blanc massif is the highest mountain range in Western Europe and has 11 peaks over 4,000 meters in France and Italy. Every year, hundreds of thousands of tourists visit the mountain range, according to the BBC.

It is currently impossible to predict exactly when the mass of ice can collapse, according to experts from the regional government, Valle d'Aosta, and the Fondazione Montagna Sicura organization.

A few days ago, dozens of people attended a funeral ceremony for the Pizol Glacier in northeastern Switzerland. This summer, a similar ceremony was held for the Okjökull gazaar in Iceland which in recent years has melted and disappeared.
