Alta: a truly remarkable video of a quick clay landslide in Norway


One of the top ten landslide videos of all time was captured yesterday at Kråknes in Alta, in the north of Norway. This video shows what is almost certain to be a quick clay landslide. It occurred in the morning of Wednesday 3 June 2020; the video has been posted to Youtube. If this video ceases working then it can also be viewed here.

VG.no has an article (in Norwegian) that explains the context of the video. It was collected by the owner of one of the houses, Jan Egil Bakkeby. He notes that they saw a tension crack downslope from their cabin on Tuesday evening, but chose to stay overnight. It rained on Wednesday morning, after which the landslide occurred. He fled from the house and climbed the hill, and then shot the video.

Quick clays are glaciomarine materials that have strange properties. When disturbed they are very weak – indeed their behaviour is similar to that of a fluid. But undisturbed they are much stronger, primarily because of the role of salt, which glues the particle structure together. When this structure is disturbed, the quick clay rapidly weakens, allowing these spectacular landslides to form.

I have featured a number of other quick clay landslides over the years, including examples from Sweden, Norway and Canada, and a similar type of landslide from Brazil. The most famous example is the Rissa landslide, also in Norway, for which another excellent video is available.

Kudos to the builder(s) of that white house.

They should use it in their advertising commercials “This is how the quality of our houses hold up to extreme conditions, call xxx for... :flipoff2:
 
The debate over whether that was caused by climate change or covid-19 is gonna go on for a while...
 
that's neat.


"If the house survives, do the property lines get moved? Can you just claim the new ground where you land?" :laughing:
 
Poor bastard can't even rebuild (or relocate) his house.. his entire piece of land left him. It's like the ultimate c&w song :laughing:
 
I want to know the brand of RV I mean shit if that thing could ride all of that turbulent water and never tilt left right or sink. That thing is pretty solid itself. I quit watching the houses after the first 3 folded like nothing. That thing just held its own the entire time and even the headlights and grill were above water.

Where's Lil Uzi, the resident geologist, to diagnose what happened?

Get an expert analysis from him.

on my farm, a creek that is spring fed and about 15 miles long cuts through the back side of my property. it's 70ft from top to bed in some places. there is an old bed (that is also on my property) that acts like a ditch.

back when the creek was in that old bed, I guess it hit rock bottom and quit eroding while the rest of the creek kept eroding. it found a new, shorter path and that "old bed" has a small waterfall due to the rock bed.

well, there is a ridge that rises about 120ft from and is maybe 1/4 mile along said "old bed". the entire side of that ridge on the old bed side slid and closed in that old bed. This was a few years ago. But the bottom moved about 15ft horizontally and at the ridge top, it dropped about 6ft on average.

I'm guessing water just sat on top of that rock and reduced the friction.

problem with all of that is we had a deer stand we called "the tower". It was an 6'x6' on cedar posts and the "crack" at the top of the ridge starts right where it is and it's now leaning something like 20*
 
That's crazy. It must have been soil sitting on a huge sloping slab or something like that. Those houses are not new. I bet that some of them have been there for 60-70 years or more.
