Mount Ruapehu Volcano Update; Alert Level Raised in New Zealand
Vložit
- čas přidán 21. 03. 2022
- The Ruapehu volcano in New Zealand is showing signs of unrest, as increased earthquakes have occurred alongside rising temperatures at its crater lake. As a result, its alert level was raised from 1 to 2, indicating a change from green to yellow. This means that a phreatic eruption could technically occur with little or no warning. So, is an eruption likely? What is the context of these earthquakes? This video will answer these two questions, and discuss what might happen next at this volcano.

Mount Ruapehu is undergoing an increase in activity but in all likelihood will not erupt. These increases occur about once every 6-18 months, and typically end with no eruption. Also, I am keeping a close eye on Sao Jorge in the Azores as I just detected some uplift.
La Palma Repeat
What supervolcano do you think will erupt most recently?
"Stay away outside of a 2km radius because of the erupted lavabombs in the past." Okay, that is understandable.
The other thing is the crater lake. If an eruption will occur, the lake will perhaps overflow and the then hot water will rush downwards farther than 2 km. Or do I see this wrong?
However, if I were there, I would stay farther away than 2 km, at least in valleys.
Nice video, thanks. 🖐🏼👴🏼
@@OpaSpielt why would the lake overflow when the heat from the magma rising would vaporised it immediately
@@farhanatashiga3721 Perhaps you are right. But I would not take any risk. I don't think it is a safe bet.🖐👴
An absolute must for volcano travellers. A guided walk from the ski lodge on Ruapehu will get you to the crater rim and lake below. Next door is one of the best walks in the world at the Tongariro Crossing which will take you along and past many active volcanos, especially Mount Ngauruhoe (called Mt Doom in Lord of the Rings films). You can do this as a side trek if you have the energy and explore it's active fumaroles near the crater summit. With Lake Taupo (super volcano) nearby it is a must.
Paul this sounds awesome
Stayed in a hotel at Taupo overlooking the lake. It's an amazing sight to wake up to a snow-capped volcano far across the lake on a sunny morning.
With the raised alert level there now a 2 km exclusion zone around the central crater rim meaning the guided climb (its much steeper and more rugged to be described as a 'walk') where you can see the lake is now not possible. This doesn't effect the Tongariro Crossing, though we are now heading into the southern winter come June, where the crossing becomes an alpine/mountaineering route (so need how use crampons/ice axe and best done with a guide if people are novice mountaineers. Finally the area is very sacred to local Maori (who traditionally prior to european settlement wouldn't even look at the mountains from a distance) and summiting of Ngauruhoe is now very strongly discouraged.
There are volcano travelers?
@@rong1924 Well I started 26 years ago. I know there were a few companies that did it then, although I did it solo.
cheers...it can go at anytime with no warning..my mum lived in Ohakune growing up with the mountain seen from the front door..1953 eruption ,her dad had to get up on roof to sweep dust and rocks off.
Wow - I think Ohakune is quite a bit further than 2km from Mt Ruapehu!
There are large signs in the ski lodge telling you where to escape to in the event of a mud flow at the Whakapapa ski area which is 3 miles down the North slope of Ruapehu.
Magnificent volcano that one, I once stayed half way up the mountain in a lodge for several nights as a young fella for a school camp. That was an amazing experience.
We stayed in The Chateau - the white building that could be seen next to the volcano during this video - in the early 2000s. We took a drive up Ruapehu. It's very impressive. The Tongariro National Park, of which it is a part, is a fabulous place to visit, with Tongariro, Ruapehu and the perfect cone shape of Ngauruhoe within the boundaries of the park.
Your sober and science based assessments of volcanic and tectonic activity are much appreciated as opposed to the lunatic sites that predict disaster at the slightest shrug of the Earth. Change nothing, sensationalism is very tiresome
I use to love visiting Ruapehu for the snow... After Whakaari I've been reminded this is an active volcano. Ive lived in the South Island for the past 4 years and forget the big mountains in the North are in fact mostly volcanic.
The big stand alone mountains, but the bulk of the big mountain ranges up to 1800 metres)which run up the east coast of the North Island are almost all non volcanic in origin.
Yup also can't believe that Auckland is built on a volcanic mine field ( though I'm not sure if they will ever erupt).
I was up at the Crater Lake viewpoint about three weeks ago. It was just steaming peacefully then. I highly recommend this walk but wouldn't do it right now! The views up top are beautiful. You can take the gondola up to the cafe and then walk up the partly untracked mountain to above the Crater Lake. Took about 4 1/2 hours up and down including stops for pictures etc. As other commenters have mentioned there is the fantastic but usually very popular Tongariro Crossing daywalk nearby - or you can do various multi day walks - is a beautiful area to hike in New Zealand
DOC have imposted 2 km exclusion zone which prevent views into the crater where you can see the lake.
I don't know if its known but a video about the fastest growing volcano would be interesting.
That would either be Bagana, Arenal, or Mount Pico. I am not sure which of the three is the fastest to grow.
Would be interesting to hear about Ambrym Volcanos history & its ongoing heightened alert level.
I plan to cover and eventually visit the volcano in person.
I'd be more worried about the Super Volcano next to it .
Yay! New Zealand makes GeologyHub again!
I just wish we had loads of dinosaur fossils like the UK has. They're quite rare here.
lots in Hawkes Bay
@@chrissy7033 They are quite rare in the Bay, there barely been more than a dozen fragments found.
Volcanoes tend to bury things ... yes.
@@matthewaislabie7354 it's not the volcanoes for the most part, it's that the islands are essentially the plate boundaries so there is a lot of movement both breaking up fossils in earthquakes and subduction taking them deeper underground
What a stunning mountain! Thanks for the very interesting update and helpful graphics.
There's not just Mt ruapehu there. There are 3 volcanos in a 20 km radius Mt reapehu, Mt ngaurwheo and Mt tongiroro
The correct Maori spelling isn't hard to look up - Ruapehu, Tongariro and Ngauruhoe. Also techincally Ngauruhoe is part of the Tongariro complex, plus if you using the 20 k radius there something like 10 or 12 volcanic vents, though some are very eroded. Pukekaikiore, Hauhungatahi, the Tama lakes complex, on the other side of Tongariro, Rotopaunga, the Pihanga and Kakramea peaks towards lake Taupo, which itself is a series of massive collapsed volcanic vents.
Your voice and the different tonality and cadences of your speech seems to have a hypnotic effect on me...
I'm genuinely curious about the effect and why it happens.
It's almost like asmr but I am thinking about the subject at the same time.....
Are you some kind of wizard or have I accidentally found a new kind of meditation? Lol
Stud factor doesn't apply to Hugh only😂🤣😂
Gonna have to disagree with you. I love the videos, well done, well researched, always educating, and amazingly fast output related to current events….but I have had to stop watching a few due to the, dull, monotone, yet somehow, over-exaggerated pronunciations and fluctuations of certain words and sounds. Sorry man, but consider it constructive feedback. 😘
Great channel..thanks for the videos.
Very nice summary!
This channel is a 7 course meal at a five-star restaurant amid a sea of CZcams junk food. All the different aspects of the many varieties of volcanoes and the history and current conditions are fascinating.
In all my life I was afraid of volcanoes but this video has given me the courage to jump into an active one. Appreciated.
That's the best pronunciation of Ruapehu outside of NZ ever. I'm impressed.
Thanks for the warning, and I'll make sure to keep at least 2km away from the crater of the Ruapehu Volcano. This should present no significant difficulty, as I live on the other side of the planet, have never visited New Zealand, and have no plans to do so, ever.
Thanks for the update I was the one who asked can you do a New Zealand volcano update
You are the Volcano Master. Thanks for your exceptional videos!
*correction, white island is the most active volcano in the country (not just the north island, south island has no active volcanoes), but doesn't seem to be by numbers because one eruption went for like 30 years straight.
I've climbed to the summit of Tahurangi 2797m twice, once from the north and once from the south . The views across the crater lake and dome, and summit plateau are great. Taranaki visible to the SW.
Southern end of the T V Z , activity ongoing, climb with respect.
Bro,how about a detailed analysis of the earthquakes on east side of Taiwan, I'm interested in the movements of the three plates there and the energy released
Please do not address a volcanologist with bro. Try Sir.
Ruapehu has a major eruption about every fifty years or so, nothing unusual for us
Pretty much, its just doing its thing.
Brilliantly done. Great information!! Thanks so very much!
Very interesting thanks!!
Hi! I’m interested in reading more about the subduction and rifting you mentioned, do you mind posting some links?
Lonquimay in southern Chile was also raised to yellow alert (2nd lowest of 4) because of an increase in seismicity, especially hybrid quakes. There are no signs of an impending eruption, but if it occurs it will likely fissural from a system adjacent to the main edifice (like in 1988) or on its slopes.
I’ll most likely cover this in my weekly news segment :)
@@GeologyHub if you don't know (strange) where to get the reports with the technical details just let me know
Oh boy baby, I love Volcanos! There is just something profound about them. Do you have a favorite type of volcanic eruption? I know I do, it is phreatic eruption. Just the thought makes my knees wobbly and my heart flutter. So quick so powerful. I live so close to several potential players here in Northern California. Love the show. It just keeps getting better. Production quality has gone through the roof and plenty of diverse topics to keep it fresh.
First volcano I have heard of with a clock! :)
I see this volcano every day so I'll have to keep an eye on it, just in case
Be sure to not turn your back to it, you might miss it!
The best man/geology interface is right here. As always, thank you!
i like your new vent blockage animation !:-) 🙏⚡️
What are the main threats if this volcano erupted also I don't know if you have ever done a video on this but if you could go back in time to watch 5 historic volcanic eruptions which eruptions would you choose
I would like to see a video on the tweed valcano...
I was just there a few days ago 😳. That’s alarming. But it’s beautiful up there
Mmmm. Perhaps Ruapehu would be better described as NNE of Wellington, not NNW.
We must throw the Ring in the fires of Mt. Doom!!!
Saw the video was about a volcano in New Zealand, came for a LotR reference. Thank you for not disappointing.
Mt Ruapehu isn't Mt Doom. The volcano next to it is.
New Zealanders are sick of this shit
Makes me think of the plug that stopped up pinatumbo in 92..... Could be more like sufre hills though... Definitely a dangerous volcano though either way. Great content look forward to all your stuff. Thanks
Did you mean Pinatubo? 👀
Have you done Mt Sanford yet? It's very impressive.
I have friends living in New Zealand so will send this info on to them also.
I knew I had heard of this volcano before. It is the one that erupted and caused the Tangiwai train crash in the 1950s.
Yes, although technically it was not an eruption. In 1953 the water temperature rose and melted the ice in the wall of the crater lake. The wall collapsed and a huge torrent of water cascaded down the mountainside and washed out the foundations of a railway bridge just in time for the overnight express to come through and attempt to fly. It did not end well. I was 10 at the time. Blessings from New Zealand 🇳🇿.
@@ronashman8463 Thank you for the correction!
2007 - most recent lahar at Mt Ruapehu. Caused by lake temp increase & crater rim collapse. Super interesting - lahar was forecast to occur & a lahar spillway was engineered. I think (not certain) Geoff Mackley has video archives of the event.
I've read that during particularly quiet times one could swim in the geothermally heated crater lake. Its definitely something I'd love to try some day, but I doubt that would be possible considering just how active the volcano is currently. Hopefully the lake remains and the volcano quiets down a tad over the next few decades.
I would not swim there as its pH is 0.8.
Yeah, I would avoid doing that if at any time it could go from a comfortably warm temperature to blowing like old faithful. I've traveled all over California, Oregon, and Nevada specifically to visit hot springs, while always being cautious of the boiling frog effect.
@@GeologyHub Yeah, it seems like this was a thing before the pH got quite so low... from what I can gather timing is key, and I doubt it has been swimmable for decades. But if conditions ever stabilize to what they were when folks swam in the past, with more reasonable pH and safe levels of activity, its definitely still something I'd go out of my way to try.
@@StuffandThings_ I used to swim in Hot Creek California in the Long Valley Caldera in the 1970s. Then in the 1980s things started heating up at the hot area of the Creek. "A River Runs Through It" movie was filmed there and Hot Creek even in the 1970s was famous for its trout fishing. I used to backpack up the canyon and spend the night. There was an area of the creek where it was too hot to swim even then, but it grew and then it started having the occasional geyser in the creek until they closed it in 2004 before someone got caught in one.
Up until 1968 it was a nice swim with snow cat tours being provided. I have some old marketing photos of this. Since the 1969 eruption the lake has been too acidic. 2 Skiers in the 90s were caught in an avalanche on the Pyramid slope and were dumped into the warm lake. Thier ski clothing was perishing by the time they swam ashore. In 2006 a helicopter crashed and the pilot, a mate of mine, also experienced similar perishing of his clothing and the helicopters aluminium components were eaten fast.
Do a video of of the Cerro Negro cinder cone that erupts often in Nicaragua
Could you talk about Mt Royal Montreal QC Canada?
I went right up to the crater lake of Ruapehu a few times when I was younger, I'd be interested from our Kiwi friends whether that's still possible?
No it's not possible the iwi has stoped it . It's scared to then
In addition to what Daniel says, due the various very violent eruptions in the last few decades the lake is surrounded by very unstable, crumbly rock cliffs which are at the lowest 50 metres pretty much straight down, there no easy way to get down to and back out of the lake with risk of being killed in a rock slide.
@@user-uy6uc5ey5q I reckon there were people bathing at the edge of the lake too, but I don't remember getting to the lake as being particularly difficult, but this would have been in the late 1960's so maybe it was a quiet period for the mountain.
@@nevillebartos2858 It was quite time. There was also much more glacial melt into the lake well. I remember seeing a glacier survey study from the late 60s when I did a geology paper and Ruapehu has lost a significant about of long term ice mass from the summit zone. Obviously more ice melt means more water and this would neutralise the pH of the lake a bit as well.
Will the Hunga tonga volcano will have a possible eruption?
Good pronunciation of Ruapehu (Roo ah PAY hoo) but it's Toe poe for Taupo.
Temperatures continue to raise early April..36 degrees..
Crater lake is at 39 c degrees & steaming from lake seen today rising to 1.5km high & strong tremor continues 🤔
Volcanic rock has been found in Taihape (further away than the 2km zone you mentioned)
Volcanic rock is found all over NZ, Otago and Banks peninsulars are both former massive shield volcanoes. If you referring volcanic 'bombs' material around Taihape and not various types of ash deposits (a lot which come from Taupo as well as the central plateau mountains) they wouldn't be from recent (in geology thats like in the last 25000 years) eruptions.
Cant see the chart at the end. video thumbnail overlay on top the the info
I agree.
Would like to hear about barren island volcano
I feel sorry for the ski operators on Ruapehu after 2 years of no tourists because of covid and now this. I've been skiing there a few times over the years.
The summit 2 km exclusion zone is well away from the ski field boundaries, and it very unlikely any eruption on current conditions would have effects outside the central crater area and possibly the Whangaehu Valley ( on the desert road side). Even Tukino is unlikely to have issues.
Steam powered eruptions if its having harmonic quakes caused by steam rushing around like a whistling tea pot on the stove. But now it's gone quiet. Are the internal passages clogged from a collapse. Is it building steam pressure. Will the steam pressure expand and cause the in rush of the lake water into the magma chamber where the almost instant flash to steam blows the top off the pressure cooker. Oops volvano..
I wonder if the first shockwave from tonga eruption was downward as an action creates an equal and opposite reaction...
Apparently New Zealand is still under construction.
This volcano is notorious for destroying a passenger train back in the 50s
There was no warning system back then.
Think it's still our biggest train disaster
@@mikefrederickson9437 which was caused by a volcano erupted which cause a lahar
I live below Taranaki there's a few spots on the farm where I can see 4 Volcanos the history's awesome
I tried watching this but can't get past your voice 😳
bruh I only got to ski once last year and now my ski trip is threatened by Ruapehu erupting
The lava shown at 1.35 is most likely andesitic and NZ volcanic region comprised of rhyolitic rock which produces volatile explosive eruptions rather than a smooth flowing stream of lava. High school geography.
friendly reminder if you're on the volcano in the ski fields when it erupts, immediately get out of the valley when the siren sounds. you can not outrun a lahar regardless of how fast you think you are on your skis or snowboard. should ash start erupting out, don't be silly and start filming, get out and evacuate.
What local volcanogists did you speak to? Wonder if it's one of my lecturers haha
Im from new zealand, this is rather common to us here. We live on a very active volcanic bed. Our entire country was made from volcanic activity
NZ is made from tectonic plate collision of the Pacific Plate & Indo Australian plate causing the land uplift of the Southern Alps. The plate collisions are also responsible for the friction & heat source that is causing the volcanics in the North Island. There is no volcanic activity in the south island but many earthquakes from fault line movements. Mostly on the Alpine fault but some from off shoot faults. Like the earthquakes that shook Christchurch.
Why does Ruapehu look so strange for a stratovolcano
Its technically a composite andesitic stratovolcano, and its had distinct period of varying types of eruptions over its 250 thousand year life which have created different vents (and rock types) at various places around the current mountain. When you add on top that the mountain been heavily glaciated particularly during the last glacial maximum and even today it has glacial remnants on its high slopes all have combined to create it current shape. Ruapehu has had a very complex geology, not least as it lies a short distance from NZ largest volcano- Lake Taupo.
This mountain thinking of doing a little trolling
Kaboom
This Volcano look like magnificent
I think he should be super Volcano in the future or I'm wrong because the Volcano look huge
there's a super volcano next to it
I'm moving to the northern island sometime in 2024 lol honestly I would love to see an eruption
Just our friendly local volcano doing its cycle....
The beacons are lit!
Can you guys do a video about the lake tarawera explosions and how it destroyed the pink and white terraces which were considered the 8th wonder of the world
Just one quibble... since you did in fact note it, it must have been noteworthy. Or else you would have skipped it.
its always funny hearing people not roll the r like you're meant to
When I get angry the mountain gets angry why is that
that one always plays up the 2005 moment it pop was cool it the daddy one people need to worry over as if that pops the north island will be gone lmao
Taupo is pronounced Toe-poor by the way
I live there :)
i hope it blows up and im in the centre
Ruapehu, being a menace to South Central.....
RUApehu, not RUHUpehu.
I expect it'll have a covid cough ;)
please please please change the anchor or the voice.its not good.
Expect a cough.
Longer term eruption will eventually happen as heat generated from subducting plate movements over the last few years starts to rise magma.
Yet we can't get a clear picture of Bigfoot!!!
Damn Balrogs
TIL not all faults are caused by shearing action 😌
This is an example of subduction, not shearing.
rhuhupihu
? Thank you people my grandfather built island white in California. Long beach thank you Bo-bo
if its not note worthy.... why make a video on it ?
What's to stop it from blowing like Tonga? If Planet X is tugging at our plate tectonics, anything goes.
It erupts reasonably regularly so there is no worrying amount of magma build-up.
@@louisej3664 "If Planet X is tugging at our plate tectonics" - nope.
planet x doesn't exist, the only thing tugging on our mantle is the moon
@@TheDanEdwards lol
How the hell is "Rua" pronounced "Ruhu" and "Ruha"
It's not, this guy just can't pronounce it
Hello, you cannot have any Volcanic Activity because the HEATERS that supply heat to the MAGMA are turned off. So there is no longer any TECHTONIC PLATE MOVEMENT as a result. The MAGMA is a layer inside the outer shell and is designed to prevent HumanKind and Sentient Kind from digging through to where the Gravity Crystals are. The TECHTONIC PLATE MOVEMENT is as a result of the Comet that was used to start the ICE AGE Shattered the outer shell. This caused TECHTONIC PLATE MOVEMENT. The HEATERS are WORMHOLE DOORS that connect heat in bursts from the Suns upper atmosphere to the Planets Magma Layer. The WORMHOLE DOORS are now closed so it is no longer possible for the Plates to move and it is also no longer possible for Volcanoes to Erupt. This also means that there will no longer be any Earthquakes or Tsunamis. You'll still have GEOTHERMAL ACTIVITY though. Earth is the only Planet in the Universe to have GEOTHERMAL ACTIVITY. I am the Arkangel Daniel and I am from Heaven.
You're a funny troll
I give this 6 out of 10 on the timecube scale. Seek medical assistance.
@@thomasneal9291 I'll say it to you in a language that you understand "NIEN!" And you are M2 William of the GESTAPO who is a dork and knows nothing. Do you still have 2 left feet? I am the Arkangel Daniel and I am from Heaven.
Hail zealandia
Omg I love how you yanks try to pronounce New Zealand names and places , u have to roll the R rrrrrru-a 😂😂😂😂 points for trying lol
If only you could pronounce the name correctly. It sounded different every time you spoke it.
There is this dude clickbaiting about it, but I don’t think he realises that this volcano has previously killed around 130 people after destroying a train bridge
