- Mt Ruapehu, New Zealand, March 18, 2007 After months of signs that the long awaited tephra dam collapse at Mt Ruapehu's crater lake was imminent it finally happened on Sunday March 18, at the time I was, amazingly, in Turangi, only 30 minutes away from Mt Ruapehu, a helicopter was quickly organized and within minutes I was in the air above the lahar, extensive, exclusive video was shot... enjoy !

Wow ... that is an amazing video. Especially because my wife and I were standing on that exact spot 2 days ago, looking at the Tangiwai memorial and reading the information board that you see between 5:45 and 6:30 ( and also at the very end ). She was having difficulty imagining the destructive power of a Lahar ... this video shows it extremely well. Thank you so much.
It is amazing how powerful something as soft as water can be when it is combined with gravity and rocks.
We were on the ferry crossing Cook Strait when it let go and made it there the next day . Day three we took a scenic flight over the crater. What a sight!
We live in a volotile country.. my dad was in the rescue party of the Tangiwai Disaster.. sad but true 😔
Your dad? What was his name?
Now us Kiwi's know what kind of hell those people in the Tangiwai Disaster were facing back on the 24th of dec 1953. 151 lives lost when the train bridge collapsed minutes before the train crossed due to a lahar in the same river (Whangaehu river). the bridge you see on this video is a few metres away from where the original stood
But why were the trains still running while there was an event going on? Not trying to be snarky, really want to know.
@@regular-joe Fair question. I don't think they knew much about lahars at that time, and how destructive they can be. I also don't think that they knew how easily and frequently Mt Ruapehu can create lahars (and that many of them come down the Whangaehu River).
All of that meant that at the time there was no warning system in place for lahars.
( I *do* remember reading about a guy who had just driven across the road bridge at the time - before it failed - and saw both the lahar and the light of the train approaching in the distance. He tried to flag down the train, waving wildly by the side of the tracks, but his brave effort failed. )
Fortunately, there *is* a warning system now in place for Mt Ruapehu and it works well.
A very impressive demonstration of the power of these things.
I do just remember the Tangiwai disaster; it happened while the Queen was visiting NZ.
really nice helicopter camerawork, I love this!
I love your videos. Simply the power of nature with as little dialogue as needed.
I visited the site a week after the lahar. Smelt like Rotorua. Awesome footage
THIS lahar is actually much smaller than the 1953 one.
I had a friend who was in the NZ Army at the time, who was sent up as part of a demolitions force just 2-3 days later.
He said there were boulders there as big as a house that they were asked to blow to pieces.

Behind where the toilets were (at the Tangiwai spot) there was a dirt walkway and a grass spot where you could look up stream towards the bridge - there was a fence thing there. I went back some months after this and where the toilets and track were was a big mud like hill and it covered the fence posts so you looked at the bridge up stream higher. That's how I knew how big it was. I underestimated what 1 million cubic litres of this stuff could do as a 12 year old.
@jabrams45 until you found out that this is boiling hot mud XD
CRAZY!! I Was here last week and it looks messy still but paid my respects xox
There was realtime monitoring of the dam/lahar path (cameras, flow monitoring stations, etc), as this lahar could affect two major State Highways, the main north island railway and a set of hydro-power-station water intakes. The event was identified in seconds and a preset plan put into place.
Engineer who rebuilt the bridge after the disaster certainly did their job terrifically
If you are patient, you will see a full size single track railway bridge for perspective. This is a replacement bridge for one that got taken out in 1953. It also shows a toilet block being covered in mud. And other similar stuff. It is a big fast mean as hell lump of dirt rocks and water.
Me and a friend are filming a short doco for a school project and were wondering if we could use this clip in it? Cheers :)
a side of the crater lake gave way sending it all down the mountain
Very impressive. It reminds me of the lahars generated by the Mount St Helens eruption on 18 May 1980, though they were much bigger, much more destructive and were caused by an eruption on the day. It would have been interesting to be in the hazards monitoring team tracking the progress of this event. How long after the event started did you find out that the dam had broken?
amazing Lahar, in Mt Semeru every Year on Rainy Season alway produce of Lahar
Nature loves to move stuff around and change things from one form into another into another. Sometimes slowly, sometimes quickly.
Anybody want to go swimmin'?
Great footage!
Such a tragic waste. Willy Wonka must have been devastated.
Lol
Incredible video we sure live in a troubled world (as demonstrated by the forces of nature around us.)
When you see somthing like this approaching you know this is not gonna be your day.....
Must be hell for the people around.
Surprising volume of water in the crater lake!
Water weighs 8.33 lbs. per gallon. Lahars are much denser and therefore much heavier. Nothing would survive in that.
Same density as mixed concrete
Incredible! Well done! At first i thought it was mt. St. Helens.
Wrong geographics.
Thanks. I was aware of the preset plan to mitigate the risk and manage the response to the lahar event. I am also reasonably familiar with the Tongariro National Park and know about the infrastructure risk. Whilst I could probably have assumed camera's had been set up, I had not heard anything that I could recall i n the media items that I had read/seen about this issue.
1 Day before I was standing still at the crater before the outbreak, not even 18 hours later the explosion came
When shooting footage, especially of something so dramatic, you need to include some perspective, to set the scene, especially for those who don't know the area. Show some horizon, pan around, etc. to set the stage and help get a sense of scale.
+Mon Hug - It's absolutely incredible footage, of that I agree. The person who shot the footage went to some trouble and expense, and based on the description it looks like they intended to share this footage with an audience, so they were thinking of others while shooting it. And that's wonderful, of that we can all be thankful. As a photographer myself, I simply intended to comment with a tip, that the photographer might appreciate, since we all like to make the most impression with our work. Consider my comment above as being in a helpful tone, not a mean one.
+Mon Hug - Well I do get paid to take photos for technical inspections, and I have been looking through the lens of a camera for 40 years, but maybe I'm not what you might consider a "professional cameraperson". I take landscape photos as a hobby. And I did make my comment on this video with no other context and knowing nothing of Geoff or his other work, so having reviewed his other stuff JUST NOW, clearly he's well qualified. But in my defense, one does not have to be an artist to make a comment about a piece of art, and what would be the point of art or creations if only the pro's in those disciplines were the only ones considered worthy of commenting on it. A piece of work that is showcased on such a public venue as CZcams can be critiqued by anyone - we all have opinions. Probably a professional would not be concerned what an "amateur" thinks of his work anyway.
This is a good exercise to illustrate that maybe we should just all stick to making fluffy rosy comments and never anything critical. My comment is barely negative on the scale of things considering all the dreck that flies around on the internet. Sheesh.
Finally, I've found someone intelligent on CZcams...
+Lisa Simkins They were probably too busy running away from the lava flow to worry about trivialities like scale Lisa. And most of the scale would have been scraped off anyway.
+Boro Nut . Actually he got most of this amazing footage from a helicopter. What I meant by scale was to include something like a quick shot of the landscape, horizon or some feature near the start to give the viewer more impact about how big the flow really was. Minor point :) He shows more landscape to set the scale later.
I wonder if the rail bridge shown survived, the camera left it well before the lahar reached its peak
voicey99 it did survive, it was built to withstand the lahars following the original one being washed out in christmas eve 1953, which cause the tangiwai rail diaster where the wellington to auckland express plunged into the river killing 151 people
Our introductory books too often simply fail to mention this a possibility as falling under the lahar label. They focus on hot lahars which happen as the snow melts during an eruption. However, cold lahars can occur too. Heavy rain bringing down the pyroclastic material off of the slopes is also a lahar. This would appear much like a flash flood. Here, we have a case where a volcanic dam breaks, releasing the water trapped on to of the volcano, bringing the pyroclastic material down the mountain. See the USGS page on lahars for more detail. volcanoes.usgs.gov/vhp/lahars.html
Awesome, thanks
Great work, BUT: For the first 2:30, when the heli flies by, I had no idea abou the size of that flow. Was it small and you were 30feet above it? Was ist big and you were flying at 500ft? Then there was that other heli, then the roads and I went oops. That's really big, really fast and definetly a lot of mud and water...
Awesome!
thank god im not living in seattle. Mt.rainer blows its top,this very phenomenon is gonna wipe seattle off d map
So true. Rainier won't blow-- it will melt some glaciers and the mudflows will go barreling down the valleys like liquid concrete 50 miles an hour and 100 feet deep as far as Tacoma and Seattle. The town of Orting will have about 40 minutes notice if they are lucky.
There's very little chance of a lahar wiping out Seattle proper, though other cities south of Seattle are certainly in the danger zone (around the Tacoma swath). Check out hazard maps for Mt. Rainier.
Then imagine yellowstone. Not just Seattle but the entire US will be wiped off the map
january 2021 peeps??
The 40+ here may remember the devastation caused by lahars after the eruption of the Nevado del Ruiz (Colombia) in 1985. The nearest town down the valley, Armero, at 50km distance, was obliterated and virtually erased from the map by them, as well as 3/4 of its 28,000 inhabitants by them. Other villages along the streams were affected too.
None can also forget Omayra Sánchez, the girl from Armero trapped at the knees in the concrete-like mud for 3 days, before passing away. The Spanish journalist Evaristo Canete captured her in video after she asked to say a few words to the camera: she asked her mum to pray for her to be saved safely so she's able to walk again. She was never saved.
Still hunts me to this day. It was broadcasted in Spain on the current affairs tv programme "Informe Semanal" over 35 years ago and I still think of her sometimes.
If we set foot in it... what would happen?
You wouldnt be able to stand since they have the consistency of wet cement and when they're caused by pyroclastic flows melting a glacier they're boiling hot too. Impossible to survive in
@AndresPajaro no. im learning about them in cemistry now there just a massive mud flow. usllaly caused by a volcano eruption. there not hot.
That’s a Lahar!?
I like lahar footage! But y'all never show the source for context!
It’s not an easy thing to get video, incredibly dangerous conditions surround events like these and the closer to the source the more dangerous
On video
en.wikipedia.org/wiki/Mount_Ruapehu
Amazing.... being there must have been special. Was it a river or a baranco? Any life in a river would have to start from scratch ...obviamente
A little late with a response, but all the same. It is unlikely that there would have been much in the way of life in the river as it is acidic as the source of the river is a crater lake near the top of Mt Ruapehu.
en.wikipedia.org/wiki/Mount_Ruapehu
Wow
Amazing. Look for the bus stop at 6:00. I wonder if the bus ended up late?
Probably.
Taking trees down like nothing but those tables 😍😍 Standing ovation to whomever installed those picnic tables 😐😐 they didnt even budge in the video!!!! Lmao like 10 foot rebar footings for each table 🤣🤣🤣🤣
It´s like the birth of a river.
There's no other sort of lahar, mate.
This lahar was expected but much to the surprise of volcanologists another unexpected one occurred after this.
Living here it seems like scientists are saying 99% of the time, "Something's coming! Be prepared!" (earthquakes, flooding, volcanic activity etc.), and the other 1% is, "Shit, oh no oh shit we weren't as prepared for this as people expect us to have been oh dear..."
Not hating on them, no one can predict natural events, but it is a wee bit funny
Yeah it confusing when one expert says one thing and another expert tells you something else.
WELCOME TO PLANET EARTH
Yeh ! Aint never seen so many certified volcano experts on one fuckin' page . Must be quite easy to become a volcanologist . However , it's probably a very short career . LMAO
Perhaps the fancy search algorithms for CZcams have determined under Covert 19 lockdown conditions that I have a tendency to catastrophize and that for some reason have thrown up this random Vid during this point in time..... I use to work for RAL ( Ruapehu Alpine Lifts) so I think it is fare to say I know all about living under the constant threat from the Crater Lake. I have made the long climb up the Whakapapa Glacier ( one of eight Glaciers) to the Dome a few times a couple of years before she burst the rim. I remember that the government at the time (Labour -Helen Clark) spent many a tax payer dollar to put in place and build storm banks and early warning sensors etc to avoid a repeat of the Tangiwai rail Disaster while on their watch. I understand it worked a treat, the engineers got it right and it went to plan with little damage to the bridge. Having also work for TVNZ and though I'm not a shooter I have experienced the massive vibration and horror of hanging out the open door of a chopper burning the budget and having the weight of the network on your shoulders to get the money shot. The task of trying to capture the moment on the fly. (pun intended ) in it's entirety is not an easy one I can assure you that. Specially on a heavy 700 hand held long lens and still using clunky old optical DX discs. So well done Sir . Most Kiwis had no problems with putting in in context and an establisher shot was not needed. When you are a Stringer for News thats what library footage is for ay. The toilet block getting smothered was television gold ... To end on, if you fancy the threat of a real world show-stopper catastrophe to put it all in context, check out the outer space threat from the triple star system of WR 104 , Our atmosphere and humanity will be fried in minutes and we won't even see it coming. da da daaahhh . You are going to need a long lens for that one 😂
so, was this all completely dry land before, not a river, stream or streambed?
how much of this was existing river pathways?
the footage of the bridge, that lahar increased very rapidly.
LAHAR. TSUNAMI comes down from above. Not from Sea, from Land.
Small river. This is from Mt Ruapehu's crater lake which burst it's banks.
ol' rua changi. ol' rua chaagaa.
ads? what are those? :P
La Ilaha Ilallah
So big
I see all that happens have you all see when it get dark dark also? How about all the grass happer I saw grass happen in book ...of hmmm
eating much Taco Bell be like:
That's Tangiwai bridge there has been accident the tangiwai bridge December 24th 1953 Wellington Auckland express to wards to Auckland the old bridge was wash away lahar the drive saw bridge wash away express heading to wards it the driver quickly grab the flashlight the driver waving the walking the track try stop the train the train drive saw flashlight what going on the driver and fireman brake hard but is to late the train plunge to river 280 passenger on board the train all 6 was wash a away lahar all coaches completely destroy KA 949 Was scrap 65 years later this crash and never be forget
A disaster memorial that's in a disaster.
Too close up to get any prospective. Couldn't watch to the end.
+Jim Studt At the end is where it gives some perspective.
If you keep watching you will see plenty of perspectives ffs
I agree with Jim.
Thanks. Now you made me think about chocolate milk :(.
Thats what i get for searching lahar
What is lahar?
It is made when rock, ash, and obsidian mix with water
+michael christian You could have typed that same sentence in Google and gotten a scientific and easily understood answer. The Internet can be a wonderful place for people with a fucking brain.
Sorry. Sometimes I can't stand it and have to reply. Forgive me.
+michael christian Geology student here.
A lahar is when a store of water, either a crater lake, or if the mountain's high enough, snow/ice cover is released or melted. This can be either directly due to an eruption (in the case of melting snow and ice) or a structural failure (as in here, where the side of the crater lake collapsed, releasing the water within)
Normally, this would just make for a flash flood, but what makes a lahar special is what it picks up on the way, volcanic ash, rocks, boulders. Lahars can become massively destructive, carrying boulders weighing many tonnes.
Today, footage like this will be shot from a drone, which means nobody has to go up in a helicopter and lean out of an open door. An expendable little machine can do the work, and get even better footage.
+hebneh They got cameras on the underside of the helicopters these days. Why not get several shots at the same time, and spend a few minutes editing. Why the friggin rush to post, without any thought to OUR viewing needs.
NO no
102NO
Welp this is how the tangiwai disaster happened.
me after taco bell
zooming = fail
Yes yes, whats your point?
Its like a river of chocolate milk, very scary and deadly chocolate milk...
Its a Lahar, so its ash, hot mud, water... I was making a silly joke :D
Volcanoes are so mean
I thought lahars were hot like hot ash and magma
They're water (usually from the snow on the mountain or crater lake) mixed with volcanic ash, mud, rocks, boulders. Basically it's very liquid cement.
Fortunately we were very well prepared. The trains were stopped before the bridge as we had a large disaster christmas eve 49 years ago that cost 151 lives at the same spot. (Tangiawai Disaster)
The roads had gates to stop people getting to the road bridge also. Only one farm lost access to the main road for a day. No lives lost.
🏞💚
God damned advertisement on every single freakin video now.
If you think about it he might just be walking around the sides with helicopter noises playing in the background, scale give me scale!
The worst wreck in history new zealand
THIS is flash flood not a volconic eruption?
24. The the use
Got
Incredible? No. Pretty impressive? You bet!
Mordor was destroyed, that's what caused it.
Saama Raama nah mt dooms the next volcano north
151 people were dead
No, no one died on the occasion, a previous lahar on 24 December 1953 weakened the original bridge and resulted in the Tangiwai disaster.
en.wikipedia.org/wiki/Tangiwai_disaster
hot chocolate actually
death by chocolate.
time to grab the tubes!
David Kea lets go tubing in the raging river of the mystical chocolate milk mmm
Yeah - if you're both stupid enough, go for it!
It's very difficult to get perspective on the fk9w the very amateurish taping is hard to get good mental image of .the build. Up, should have paid a perfessional, would been well worth the end results.
And P.S. Why not wait until the LAHAR was gone, so you could show us the carnage to the river system and how many structures or whole farms were lost. Bush league ammature thinking. I need more of the big picture if you want me to SUBSCRIBE.
How are they going to blame president Trump for this
Too jerky to watch!
😂😂😂👍🏻👍🏻👍🏻
penso ai poveri salmoni che vanno verso il mare cotti alla creta.
I dislike very much, the army of video posters on youtube who either show a video when saying NOTHING of what is happening, or turn off the sound altogether. What the hell is the point of leaving us to figure out for ourselves, what is happening,etc. You got a bleeding microphone,USE IT.
+tubermier I found a great resource that explains what's going on here. Full details at lmgtfy.com/?q=Ruapehu+18+March+lahar
+tubermier Mackley's a cameraman, he's not a reporter and he's certainly not a scientists.
Google exists friend.
