On the 29th of April 1978, a quick clay landslide devastated large areas of the rural district of Rissa I mid-Norway. One person died whilst 13 farms; 2 homes; a cabin and a community centre were taken by the clay masses.
Five to six million cubic metres of clay collapsed from an area of 330,000 m2 leaving a 1.5 kilometre slide face. The landslide caused great material damage to the community of Leira when a resulting three-metre high floodwave breached the opposite bank of lake Botnen shortly after the main slide.
The Rissa landslide was caught on 8 mm cinefilm by two film amateurs. This is still used actively in avalanche preventative and educational work.

At 5:05 they state the load from the fill caused the collapse but you can plainly see only the front portion fails and that failure also stretches down the coast where no fill was added. Then after the first slide huge areas adjoining gave way. So obviously the salt had been leeched out of those areas and the fill had nothing to do with this event. It was going to happen anyway. The farmer should sue for erroneous defamation.
So well done – fast-paced and no extraneous information. Well worth the time.
Early on, cue the scary music.
Mud…..flood!
5:50 I had to stop watching at this point because of the scary music. I didn't want to have nightmares.
USA could have used this info from Hurricane Katrina? How to fix a community that has been destroyed in 4 years.
An intelligently made and presented documentary. Extremely interesting and very educational.
I enjoyed this. Thank you
why are people bringing up global warming here at all? what compells one to go on an unrelated video of a 40 year old documentary to complain about climate change?
Global warming? LOL You fucking clowns, the earth has cycles. We are cyclical in nature. Keep buying the jewry!
Nice to see, some good old-fashioned documentary.?
21:16 nice smoke ring.
What the hell are glassy ears???
Very good information.
Amazing! Just look at that! 16 million years of evolution happening over the course of just a few hours!
I'm having a good guffaw at the expense of fleabiters everywhere right about now. 🙂
Song title?
I don’t know what is scarier, the music as an entire house drifts along on top of a wave of liquified clay, or the construction dude in the short shorts. Isn’t it kinda hard to move around in jean shorts that tight?? Gotta love the 70s!
What do you do for a living?
I test clay all day.
How to make yourself the most unpopular person in several township's , lol…..
amazing that the person responsible was not liable for any damages
So was this a result of global cooling, global warming, or just another example of climate change in general?
All because of Suv's and cow farts.
great documentary from an age when programmes were not dumbed down and people still had an attention span.
They blame that on climate change now lol,a normal thing for the ice to melt till next ice age.
Was there any damage?
The background music is more terrifying than the slide.
That certainly is an interesting way to pronounce the word "glacier".
Thank you for the learning.?
Wow didn't expect this to be interesting. Thought I was watching netflix or something. Thanks YT algorithm, you win this round.
interesting to say the least..
Another man made disaster
The day when a farmer extended his barn and made his town fall in the water
Excellent. That's how a documentary should be. No flashy graphics, no endless repetition, no dramatic staging — no dumbing-down, in other words. The Discovery Channel has a lot to answer for.
3:00 wait does that mean that our units might have bin claymed ^?^
Can't believe I watched a whole documentary on clay. But glad I did.
??
I blame this on climate change too LOL. Climate change is now the punching grab bag of all natural disasters if you don't know
non Newtonian fluid flow
good info on soil/earth
Guy who started the whole spiel: "Lemme just say, from the bottom of my heart,…my bad."
"How's the editing coming?"
"Oh, it's going together really well. We have some great footage!"
"Good, good. What are we going to score it with, do you think?"
"Well, I know a guy that used to do music for cheesy black and white monster movies…"
"Perfect! Make it happen!"
Absolutely loving this soundtrack.
Norway… Supposed to be so RICH! You see this machinery in the video? Yeah, that's still being used today, and is considered "modern" technology. South-west of this exact road is being worked on right now, with the exact same equipment as seen in this video. Volumes are the biggest/only difference.
The way the first barn remains is such a comedic tragedy.
My house is on clay after this I went out and bought salt to spread around the house 😛
