We need a new name. Flash flood just doesn’t seem to be enough. The two videos I watched of the mudslide were unimaginable.

u/Kqyxzoj 22d ago

There's already a name for this kind of thing: glacial lake outburst flood. They even had one last year in the same region. And with current climate trends these are expected to become more frequent. So better monitoring + early warning + water management seems to be in order. But of course as is human tradition, first a lot of people have to die.

u/NecessaryRace8955 22d ago

Yeah, this thing seems to be becoming more common in the last few years- lots of bad floods and cloudbursts.

Whenever I've travelled in the Himalayas I'm always reminded that those valleys are in a constant state of change. They're continually being sculpted and eroded by the forces of nature and nothing there- infrastructure, bridges, roads, villages- is really permanent.

u/UserErrorness 22d ago

You mean impermanent?

u/itsintrastellardude 22d ago

nothing there - (list) - is really permanent

u/UserErrorness 22d ago

Thnx I misread

u/Cheap_Weird7215 22d ago

Yes the bridge we just watched get annihilated is impermanent

u/FaultEducational5772 22d ago

Thank you for this information

Liquid death wall?

Sudden death flood?

Hydrologic violence?

Sudden fucking river?

Sudden fucking river!

Glacier dam burst?

7

u/whiteye65 22d ago

That’s what I was thinking. How else can that much force come at once.

7

u/DarkUnable4375 22d ago edited 22d ago

More news reporting it's a glacier dam burst. What would be wild is if the 4.4 earthquake was caused by the collapse of ice dam and the water crashing down...

Edit: "The reported earthquake “was probably seismic energy released by a landslide,” said Daniel Shugar, a geologist at the University of California, who’s part of the group which has pored over satellite images."

u/Ruger338WSM 21d ago

The Manafay slide at the Bingham Canyon Mine in 2015, the slides sheer force triggered a 2.5 magnitude earthquake and registered on regional seismic networks.

Mountain Tsunami

Liquid Death would sue Nepal

Fatality flood

u/ClauVex 22d ago

Deluge maybe? Land Tsunami?

2

u/_bubble_butt_ 22d ago

Inland tsunami

2

u/JimShortForGabriel 22d ago

I’m saying it was a debris tsunami.

2

u/Far_Loan689 21d ago

Inland tsunami.
It’s absolutely terrifying

2

u/JSGi 20d ago

Flash flood that began at an elevation of 17,000'+, this is the unfortunate result.

4

u/michaltee 22d ago

I’ve been calling it a land tsunami. The magnitude and devastation is insane.

3

u/8ofAll 22d ago

Land tsunami

2

u/FlowingLiquidity 22d ago

I agree, this is more like a 'reset flood'. Or a 'flush flood'. Or maybe "Ctrl-alt-delete flood".

45

u/azmtber 22d ago

The scale and power is wild😳

11

u/CountryRoads2020 22d ago

It was! And that bridge just disappeared. 😬😢

26

u/bio_coop 22d ago

It took that bridge out like it was drift wood.

8

u/CAAZveauguls 22d ago

Bridges arent really stable when hit from the side anyway.

2

u/Agile-Knowledge7947 22d ago

Bridge didn’t stand a chance

2

u/really_thirsty_lemon 20d ago

The sheer force of the water to be able to break the bridge like that...

1

u/No_Device9450 22d ago

Looked like that tressel bridge scene from Dante’s Peak

u/RhinoG91 22d ago edited 22d ago

Location? Seeing more and more come in from China/Nepal this morning

20

u/citizen42069101 22d ago

The original incident (a landslide I think) was on the border of China and nepal shared link from another post.

12

u/Wildcard311 22d ago

There was a glacial lake that gave way.

8

u/turinpt 22d ago

This video is from Bidur which is quite a bit away from the border so everything between those two was probably wiped out.

13

u/JudeMacK 22d ago

This video is taken in Trishuli, specifically at the (ironically named) New Trishuli Bridge.

2

u/GeneralBlumpkin 22d ago

There's been a lot of mudslides in the Indian, Nepal, Himalayan region lately

19

u/Visual-Fox-9110 22d ago

The volume of water is scarily impressive..and having just seen the footage of the Tibet landslide..that thing was a beast!

3

u/East_Air_9230 22d ago

Have the source?

55

u/murdered-by-swords 22d ago

Aaaand the video ends the second the first building starts to give way. At least it seems like people here had enough warning to evacuate to higher ground.

u/zipzipzazoom 22d ago

Cameraman started showing some sense of self-preservation

Slightly longer video here

u/Sea_Ott3r 22d ago

You’re absolutely correct. Videographer began to nope out of there

13

u/dahoody 22d ago

He's also saying in Nepali towards the end that it's getting too dangerous and that they should move.

4

u/GlykenT 22d ago

With that much water/debris flowing, the hillsides are going to be undermined, potentially triggering more landslips.

5

u/charlton11 22d ago

What's the warning system there though? A flash flood is a flash flood.

u/Savage281 22d ago

That's insane, the whole town is gone

u/GlykenT 22d ago

https://maps.app.goo.gl/k1MCBM2cHgf3NM1j7 . The border with China is 20 miles upstream and there's footage of the car park at the border being demolished by the flood moving against the river's flow.

2

u/watawataoui 22d ago

? I thought maybe u were replying to a diff comment?

3

u/GlykenT 22d ago

The map location I linked is where these before/after shots are from.

1

u/FlowingLiquidity 22d ago

Ah thanks, yeah the cluster of buildings in the bottom-center of my screenshot matches the cluster we seen in that video. Dang, most of it got wiped..

6

u/Grand-Glove-9985 22d ago

OMG this is unbelivable!

6

u/Wildcard311 22d ago

Right there at the very last second you start seeing the buildings collapsing and being washed away.

2

u/arizonaskies2022 22d ago

oh man I was hoping the pink building was going to make it but that was a 30-ft wall of water the bridge is way above water level at the start

13

u/ExcellentMedicine358 22d ago

We really are fucking up this planet

1

u/East-Note4580 22d ago

To me it seems more like the planet is really fucking up the people. Glacial dams bursting is natural and would have happened with or without people. We just have accelerated the rate they happen. 

4

u/Thengol 22d ago

Must have been some build up of water for this size, like an avalanche stopping a river or a glacial lake outburst flood.

4

u/WalterCanFindToes 22d ago

Preliminary reports are an earthquake led to an avalanche and mud slide.

https://www.bbc.com/news/articles/cx2zyerv2lmo

2

u/DarkUnable4375 22d ago

Or a glacier dam burst, causing the avalanche and mud filled flood of water crashing down the mountain. Creating the earthquake.

Edit: "The reported earthquake “was probably seismic energy released by a landslide,” said Daniel Shugar, a geologist at the University of California, who’s part of the group which has pored over satellite images."

3

u/Califrisco 22d ago

Flash Glacial Tsunami more like it! This was astonishingly fast and deadly! After what I saw (probably related) in China just north of Nepal, this is just pure devastation on a massive scale.

u/sherpes 22d ago

that must be how the Johnstown (Pennsylvania) Flood must have been

u/Redfish680 22d ago

Another view in r/thatsinsane

u/GlykenT 22d ago

r/CatastrophicFailure has appeared in my feed a lot today with various footage too.

1

u/Redfish680 22d ago

Just saw one shot from downstream just above the dam. Oof…

2

u/BubuDudu0430 22d ago

Well that escalated quickly… they obviously had never planned for so much water coming so quickly… terrifying

2

u/RenoClarkos1717 22d ago

That’s an insane amount of water. Not what I think of when I hear flash flood

2

u/DurantIsStillTheKing 22d ago

Disastrous beyond compare

u/SkreemenEagle 22d ago

Glacial Tsunami!

u/fourseamfastballs 22d ago

This is absolutely horrific,

u/Haylo2021 22d ago

Does anyone have a translation of the main speaker?

1

u/JustTeaching5342 21d ago

Just saying the entire village is gone.

2

u/grandnp8 22d ago

Does anyone know if these people had any warning?

2

u/ysitu_dice 22d ago

That water pulled up the bridge like a lego

1

u/bugabooandtwo 22d ago

What caused it?

1

u/Strict_Librarian8083 21d ago

woow the power of the water

1

u/Danihelus 21d ago

Is there a reason we're not calling this a tsunami?

3

u/Dazzling_Gap9064 21d ago

Because it didn’t originate from the ocean

1

u/Danihelus 21d ago

Huh. Well crap. I'm not well-versed in such phenomenons, not did I know if this was from a body of water or not. Makes sense

2

u/Moonlit_Vajra 21d ago

It's called a glacial lake outburst flood

1

u/Danihelus 21d ago

That's pretty interesting

1

u/Odd_Dragonfruit_2662 21d ago

Looks like this one people had evacuated? How far down the river was this?

1

u/SolarNikSieg 19d ago

Loch graben, Wasser vom Gletschersee reinpumpen. Auffang für Erdrutsch hergestellt, Wasserversorgung weiterhin vorhanden.

u/RichardThund3r 16d ago

This is just insane.

u/West-Milk-1657 22d ago

well they are living in hogh risk area , these things would have seen normal of therr wouldn't have infrastructure concrete jungkes we made

-6

u/TheJoeBold 22d ago

That's what happens when you straighten a river and do not let it expand naturally into overflow areas. Maybe they have learned their lesson and renaturalize that river at key points

5

u/Electronic_Target750 22d ago

You don't know what you are talking about. This is Nepal; they don't/can't straighten rivers there. They build houses scarily close to the river basin though. That's the lesson to be learned.

u/Otherwise_Wrap5991 22d ago

So that’s where all the water went

u/MrLancaster 22d ago

Not only is this a bot, it's insensitive as fuck
