10 Devastating Rockfalls & Landslides Caught on Camera 

That's something I really appreciate about the Underworld bunch. They narrate without a bunch of Jibber Jabber on their own opinion of what they think about a video. Keep it up and keep it real.

Wow, that was truly unbelievable! 😂 Incredible work, folks!

Watching these reminds me of some experiments that were done with rockfalls and landslides. At the time scientists were convinced that these things had no resemblance to flows of water and other liquids and fluids, scoffing at various eyewitness reports to the contrary. This was at a time when mobile phones were very much in the future, so there few, if any, recordings of such events. They chose a dry mountain side to conduct the experiments, and during the preparations drew a large crowd of onlookers from the local inhabitants. It also drew a number of TV film crews to the site, who documented the whole event. I won't forget the result: when the rockfall/landslide was triggered, the whole lot literally flowed downslope, acting like a mass of water, even to behaving like a waterfall on the steeper parts of the slope despite there being no water present at all. Rocks of all sizes, from sizeable boulders down to dust, acted like water... something no-one thought could happen. It was a salutary lesson for everyone, not least the scientists. Further experiments, driven by disasters like Armero, taught us that some rockfalls and landslides don't need water to start them: others, depending on rock type and condition, only require a bare minimum to turn an unstable slope into a surging relentless flood of mud. burying everything unfortunate enough to be in it's path, and setting as hard as concrete once motion ceases.. It isn't just natural rock piles that can give way suddenly, either. I hadn't been born when the disaster of Aberfan happened, but I've grown up knowing about it. The trouble is that, with the human population explosively increasing, and with it human hunger for resources of all kinds that need to be dug out of the ground, more disasters like the Aberfan spoil-heap collapse are going to happen... unless, of course, we take heed of the lessons Nature kindly provides us with.

I love it how u just make countries that have disasters in the past & today (:

Thank you from The Netherlands

Even mountains can't escape gravity.

Thank you for the update, Underworld..!! 3:58 Wow, that was scary..!!

Wow 😮 good work 💯😎

Mr Underworld I suffer from anxiety and depression and yet your videos are very soothing to me. Thank you 🤜🏾

Underworld, thank you SO MUCH for your channel. I’m really interested in natural disasters and you cover them excellently! I am watching your videos back to your first posting. EXCELLENT. One thing I’ve noticed a few times is that some footage is reused and has nothing to do with the video subject. You know, wrong country video. Love your work though so please keep producing.

This guy is a perfect narrator

TY 👍

That’s some scary stuff. Mountains falling down. Can’t fix that.

#2 was the result of ILLEGAL logging in my family's province, which left the mountains unstable because the tree roots were destroyed.Many homes and Barangays were affecteed and are still today because of corruption of local COUNCILLORS who take BRIBES to allow the logging companise to devatastate our homelands! This is endemic in the Philippines.

It's rude to put you water mark on footage that you didn't take

Holy Cripes.

Thats carzy but also entertaining

I'm not sure if you've already talked about the avalanches that occurred in Costa Rica due to a landslide that blocked the Aguas Zarcas River. There are several videos from different days. It might be useful for an upcoming video. Greetings and excellent videos.

Worker safety ahead of profits? Never happen. 😢

#8 is Peru I think

산을 위험하게 관리하니 산이 무너지네요.

I saw a land slide in California that took out to homes. The entire hill slid and the home stayed together for some distance, then they just fell apart. Both home were "tagged " as dangerous and the owners were not in the homes. Just a few months before that I had watched an avalanche at a ski resort where the rangers were getting ready to blow it, then it just went all on its own. The Awesome power of nature.

I was working in the coast range forest in Oregon. We drove up a new logging spur road to figure out where we were to work the next day. The next day we drove up the road and found the road gone were we were going to park. The hillside had slid out. A little scary.

This is the Whoa ! ! Channel

The percentage of vertical videos feels almost impossibly high.

That is as easy as it is to bury those who think they can hide in their bunkers.

They say yodeling in the Alps can cause an avalanche. So dont yell when youre out there in the heavy snow. I see so many videos of rock slides from China, though. Must we refrain from free speech there, too?? 😸🤠😂!

1990.., ❤..,,,

Those scary moments caught on camera made me afraid to be alone

Tertawanya orang2 berbahagia ngrasa terhibur batu yg runtuh.

Before assuming the world is falling apart because this happens "so often," please remember that it's not necessarily happening more often, it's just that now, with video-capable cell phones everywhere, we are more aware of what is happening than ever before. In other words, the world hasn't changed; we have.

ليس الطبيعة هي التي تقوم بتلك الأفعال إنما خالقها سبحانه وتعالى هو القادر على كل شيئ .

Nature's wrath is both terrifying and humbling. Let's use this as a reminder to prioritize disaster preparedness and resilience.

I bought a bicycle 32 years ago. And it was stolen 31 years ago. I had that bicycle for a year. I miss that bicycle. It was green.

“Maybe next time they’ll put workers safety over profits”… yeah right 😂 sure they will!

No matter how advanced science is, nature's wrath cannot be tamed..☝️🤔

Worker safety ahead of profits? Never happen

Ja byłem świadkiem tego jak; manewr cofania radiowozem wykonywało obydwoje funkcjonariuszy jednocześnie, precyzując młoda policjantka nie była w stanie tego wykonać samemu!, musiał jej partner siedzący zboku pomóc kręcić kierownicą!

The current Blue Ridge Mountains on the US East Coast are actually the remnant of a much taller range of mountains. The Earth is a great leveler.

In India, 84k residents is a villiage. okay

yes, there werent any rabbits down there, and no precious german either

"put worker safety above profits"...... but NO ONE knew the rocks would fall that day. Maybe they could close the mine because there is a mountain? C'mon. That's where mines are.

10:13 I can't believe that's a street in any language.

Half the mountain? Give me a break it was just a small part of the mountain that fell off but I'm used to the hyperbole from this channel

La illàha illah

花蓮大地震好像刷新排名了!😂😢

these are old videos i want to see some new video instead of re watching this old stuff

👍

When are people gonna learn that you take video in LANDSCAPE mode.

第一名到底是什麼鬼😅

What’s with people recording in portrait mode? TV went from 3x4 to 9x16 for a reason, movies are in 1x2.1 for a reason, cause we like a wider field of view. Ok ok yes it’s easier to hold the phone. So then why don’t these trillion dollar phone companies rotate the cameras by 90 degrees? “Things that makes you go hum.”

yellows are clueless

What was the red boomerang thing that appeared in the center of the falling mountain 4:23 then gone 4:24?

2000,20,

Semua bencana karena ulah manusia itu sendiri

Non ci sarà pietra su pietra che reggerà

🥺🥺🥺🥺

11:53 😅 if you know.

Keto fenomene tregojne,qe Zoti nuk ka perfundu krijimin e botes.Vashdon krijimin me korigjime te herepashershme.Si jashte ne erozon ashtu dhe brenda ne thellesin e tokes.

Just wondering: Why do such a lot of people hold their camera/phone in "portrait" position instead of "landscape"? Is it stupidity, ignorance, laziness or something else??

Colorado bought her mountains from a good, Godly granite retailer. These joker states apparently went to walmart for their mountains.

Mountains be like, "Whoops, I tripped!" 😂🏔️
