Imminent monster rockslide in Brienz, Graubunden?
-
Hi,
I just read the troubling news about the imminent monster rockslide in Brienz.
Updated: this is Brienz of Graubunden and not Bernese Oberland. I was initially worried if the railway station of Brienz in Bernese Oberland would be affected.
Swiss village of Brienz told to flee imminent monster rockslide
9 May 2023
Residents of the tiny Swiss village of Brienz have been told to pack their bags and leave immediately.
The reason: two million cubic metres of rock from the mountain above them is set to come loose and crash down to the valley in the next few days.
The evacuation order has not come as a complete surprise to the remaining population of about 70 villagers.
Brienz, in the eastern canton of Graubünden, has been judged a geological risk for some time.
The village itself is built on land that is subsiding down towards the valley, causing the church spire to lean and large cracks to appear in buildings.
Work was under way to try to stabilise that and there were signs the slippage might be slowing down. But ominously, the mountainside above Brienz was in the meantime breaking apart.
Villagers had become accustomed to quite large boulders tumbling down to their gardens below.
Geologists warned that the rock movement was accelerating. Part of the rockface, innocently nicknamed “the island”, was by 2023 slipping at a rate of 32m (105ft) every year.
And yet no one thought they would have to leave so soon.
The authorities had warned of a possible evacuation later this summer, and at the end of this week a regular village meeting was scheduled to bring everyone up to date.
Instead, after latest risk assessments showed a rockslide was imminent, the order to get out came suddenly on Tuesday morning. From now on, no-one who doesn’t live in Brienz will be allowed to enter, while all villagers must be out by Friday at the latest.
On Tuesday evening, Brienz’s residents, some already with their cars packed outside, gathered for one last update from the authorities.
That innocent sounding “island” is moving even faster, and geologists now say its two million cubic metres of rock is expected to fall in the next seven to 24 days.
How exactly all that rock will fall is not yet clear. It could come down fairly gradually, avoiding most of the village. Or it could come down fast, destroying Brienz entirely.
The consensus among the villagers is that they hope and expect to come back to their homes. The problem is, they don’t know if they will still be standing.
