On this channel you will find geotechnical problems explained simple and easy so everyone can understand . I focus on disasters, landslides, quick clay, glacier bursts, eruptions but also just geotechnical engineering in general.
I have recently made videos on Mv Ever Given and the Indonesian Submarine that was found at 850 m.
Please subscribe and send me questions, ideas for videos and other comments.

There may not even be any bodies. The sub imploded.
The norwegian divers who assisted in the kursk case had a special decompression system. It enables them to dive about 400 metres! Amazing. Really brave admirable specialists
Opposite of ooblek lol
Very good video! Is there any other scenario that could create a landslide if there is no river close by?
I wonder if drilling cores to check for quick clay can set it off.
There is also a connection to the salt content of quick clay according to a video i watched on the subject.
The biggest determining factor is the salt content in the clay.......if the salt gets diluted to a certain extent the soil/clay will will liquify If you stir salt into quick clay it will solidify again
I really enjoy your physical experiments. Re: landslides in the Himalayan landslides would consider doing a video on the landslide that happened in 2015 that blocked a river for a day, which burst and sent a huge flood down the river valley.
I am advanced dummy! Thanks for the upgrade!
Sorry but this video is full of holes. Let's start with how high you can jump - 45 cm on one leg? You must be measuring from the bended position and swinging your arms for extra inertia because most people would be lucky to jump 15 cm higher than their standing height on one leg. Next there's the matter (geddit!) of how heavy you will feel. Well, you might feel nice and light in your spacecraft but you will feel exactly the same as on Earth when you suit up to go for an early morning run. Finally there's the question of walking on a very granular surface, like soft sand, where the friction is far less, so you have to put in more effort. You explained nothing!
You can learn a lot from building sandcastles at the beach

great video. thank you
Thanks for the examples of dredging 🤣. Makes things very clear
It doesn't really answer the question, why not deeper. With today's technology, there must be a way to pass 400 degrees. Rockets do it. I'd love a video explaining how we know what the layers of the earth contain. The earth fascinates me.
The boy covering the crack with his palm is the lesson which i learn in my school days. Now i am going to be fifty but still remember this lesson and love too
Their was a 6 year old who fell into a rotted out tree trunk underneath a dry sand dune, he was very lucky. Six-year-old trapped under sand dune for hours, rescued
Cool channel, I subscribed. Try to promote with G E T 4 V I E W S to get more views and subs, its official ads, without any cheating, so could boost your channel growth. Keep making videos, it turns out well.
Thank you for going into somewhat more specifics than certain other clickbaity videos (something something RLL) by at least mentioning pressure in addition to heat, plus the interesting tidbit about water. 180C doesn't seem that hot by material standards but add pressure and presumably also steam and i can understand better now that the real issue is gonna be in the bit jamming or being rendered incapable of 'chewing' due to the pressure balance, and the well casement being unable to prevent the frictional binding of the bore pipe as you try force it deeper. Interestingly the Kola borehole is no longer technically the deepest, but not by much. Based on the material science I'd guess that our best possible efforts would likely cap out maybe a kilometer further down if we poured money into a deep dig for the sake of research, but we likely cannot break through into the crust-mantle boundary zone without some utterly ridiculous material science and generations of dedicated R&D.
I don't understand why so many people say the gravity on Mars is one third that of Earth when in actual fact it is closer to two fifths. 38%, how is that one third and not two fifths?
I am led to believe that you are wrong about the causes of Quick Clay slides. The salt content of the clay is vital to the stability of the clay. If the salt content drops, the clay will liquify. Perhaps you have simplified to the point of missing the basic cause.
I think in a Scandinavian context, any quick clay above sea level can be expected to have practically all its salt contents leached away long ago, since it rains so much in our region. So I am guessing that @TheGeotechEngineer had this as an implicit assumption. The question he's answering is therefore "for fully salt-depleted quick-clay, what makes it finally slide?"
Are you German or Norwegian?
in between - Danish.
Time to make the south a double channel..
If the Netherlands wants to save its land then the Dutch government should plant as many native trees in their country as possible. The trees take water from the land and hold the land firmly by their roots. There is no better natural way than mangroves to save the land lost in the sea, and the Netherlands will have to import sand from Arab countries. At least one thousand tons of sand should be imported to the Netherlands every year in large ships and coconut trees should be planted on the shores of the Netherlands. (Suggestion from Pakistan)
Cubic is written m3
Now that you've cleared up the height mystery for me.. Can you tell me why the Netherlands are also referred to Holland? and then just to make things more confusing you don't call yourself Hollanders or Netherlandish you call yourself Dutch this really made things difficult for me in 7th grade......Just kidding thanks for nice video. :)
There were some significant landslides / slumps caused by the massive 1964 earthquake in Alaska. Although quick clay has never been blamed for these specifically, as far as I know, Alaska is like Norway in having large amounts of glacial run-off sedimentary deposits which can become quick clay.
Actually, the quick clay slide at Rissa was into a lake, not the ocean.
Tusend takk.
Since QC is made weaker by the slow removal of salt over time I wonder if all QC deposits are not equally vulnerable. Rissa was just waiting to happen, it seems. Is this right?
You have several interesting videos on this, thank you. Question: If you know there is a pocket of quick clay, can you stabilize it by pumping salt water into it? If so, is that done?
We have a stuff called dab, that might just be the local name, if it's disturbed when wet can turn to soup but if you let it set it will turn like concrete.
We had a bog slide years ago, not sure if it's the same machanics
You did not explain what quick clay is and how it becomes more liquid due to salt loss.
very good video. Thank you so much!
i am glad you liked it.
Amazing nature. Know about clay. Never heard about quick clay.
Neither had i
As a kid I used to play in the stream with my friend. There was a clay formation on the stream bank just where the stream hit the bank at an angle digging a deep swimming hole. We made a clay slide by moulding it into a slide shape and putting water on it. One day I went down to the slide and there was a huge lake in it's place. The whole side of the hill had slid down and blocked off the stream. It must have been at least 30 feet thick and all the trees were tilting uphill. A massive amount of earth moved. It took a few months for the stream to drain the lake.
Thanks for your story
I have watched the Rissa quick clay video twice so i am an expert!
I was about to join this submarine , but I got sick my sickness save me
How did it get stuck tho
Great work, informative and useful (AS usual from you), and wonderful modelling!
Thanks.
If the Burj Khalifa was built inside the Bingham Canyon mine, you wouldn't even see it at all unless you were on the rim looking down. And if you were on the rim looking at the Burj, the top of it would be as far below you, as the ground is below a person standing on top of the Empire State Building. That is one ridiculously deep mine.
👍👍
The pink cellar distally visit because salesman fascinatingly laugh towards a obsolete brain. thoughtless, quickest nation
Learn something new again!thanks!
Great to still have you on the channel. Thanks for staying.
When I was a child my neighborhood friends and I went through a hole digging phase around the age of 9 or 10. Dont know why; probably mostly due to bordem, but the desire was very strong and almost primal despite having no other goal aside from just seeing how deep we could go. I think its something deep inside us as humans that is fascinated by it. We eventually got bored and moved on to other fascinations after a few months as children do with most things but my father never really let us dig down TOO deep and now I understand why. At the time I couldnt understand how a hole could possibly be dangerous or that something as large and vast as the earth itself could collapse in onto us since we were not fully enclosed underground.
Hi, thanks for sharing. It does not seam too dangerous but digging more than 1.5 m could easily lead to walls collapsing and killing you. Too many people die from this on small construction sites each year.
"Something deep inside us", hey?
Informative, precise and to the point. And, as usual, interesting. Thank you!
hi, thanks. I am glad you are still here
I wish I were half as smart and articulate as this KZreadr! Great video! Constant education and great articulation
Hi, thanks for your feed back.
i am glad I have been able to make more good videos, thanks for all your comments.
Me: “I feel like I got 10x smarter watching this.” Also Me: Unable to teach anyone a word of this amazing science
Great. I think this was my second video.
