Erosion and Sedimentation of Taranaki Volcano
Вставка
- Опубліковано 6 лип 2024
- Taranaki Volcano stands in isolation above its own ring plain on the western side of New Zealand's North Island. It is a stratovolcano, made of layers of hard lava with soft ash sandwiched between them. This makes for a very unstable mountain and occasionally leads to massive collapses of the volcano.

Fascinating. The story of Taranaki is far more interesting than I could have imagined.
Thank you, I'm glad that you enjoyed finding that out!
That strata gives real meaning to the word stratovolcano. Thanks for this great info!
Thank you for your comment!
Having lived most of my childhood in Taranakl and having the good fortune to get to the summit on an open climb ( I hope they still have those ) I love Mt Taranaki and thoroughly enjoyed your informative video . I am living in Canada now with my Canadian husband and family , but my heart unfortunately didn’t come with me , so your video was excellent nourishment for my deprived heart with which I remain in close touch .
What a wonderful comment. I am glad this has meant something to you.
Makes you wonder who the 5 dissenters are!! Pete on the Isle of Wight.
As a child I loved visiting Mount Edmont. Beautiful land. It will always be Mt Egmont to me. Lol
@@denisehadfield7995 Me too Denise , but I do try to unite with the change of name which really should always have remained its name . When I married I took my husbands surname, but after some years I returned to my birth name because it truly is a big part of my identity . I think of the Mt Taranaki/Egmont name as going on a similar identity journey. ‘A rose by any other name would smell as sweet’ as Shakespeare put it saying that the names of things do not affect what they really are .🌹
I remember the different lava layers seen on the original ‘Desert Road’ on the Volcanic plateau in the central north island.
Very enjoyable, interesting and informative video and beautiful views of geologic structures and landscapes.
Thank you!
Has got to be your most informative video to date. Good work
Glad you think so!
So pleased I found this channel! I only wish they were much longer
Glad you like the content that much! Thanks!
Fantastic section at the beach/cliff. Many thanks for showing us what we couldn't see ourselves without a drone etc.
Thanks for your comment!
Huh, I'd never thought of the ring plain as 'remnant volcano' before. Fascinating.
Also, those lahar fields around Pungarehu always make me think of the Barrow-downs as described by Tolkien. :)
:-)
Love it, bro! Your excitement shines through. I know bugger-all about geology - despite growing up on/in an ancient cluster of volcanoes (Dunedin). I have been to Taranaki, and up the road above tree-level, and wow! Everything there is at an epic scale. Even at a glance I could see the sheer enormity of the events that shaped those slopes. But down here at the fringes, another story plays out.
I met a man a long time ago - a survivor of a famous and deadly lahar flow (he was on a train at the time), and so I certainly understand the scale of the things. Millions of them must have come off Taranaki over the years - and your presentation really captures the power and scale of those events. Keep it up!
Thank you so much for your comment and your interesting stories!
Great info, thanks!
Cheers!
Tumeke 'Out There Learning' - I just love these Documentaries that are about my Homeland & all that history Under our feet. I wish we had this type of Education when I was at school 50's n 60's instead of learning about foreigners - I get it tho would we have had the teachers to do so. Cheers & thank you 4 sharing all that awesome knowledge
Thank you for your appreciation - I am really glad that you are getting something from the videos.
Very very interesting especially having spent a lot of time in Taranaki over the years :) , I don't even know how your vid found its way to my feed but subscribed :)
Very glad that the video found you and that you like. Cheers
That's where I live and love it!
Great!
Thank you very informative great video
Thanks!
Excellent description of this magnificent volcano which I saw and was amazed by back in 1970 when as a 19 year old I hitch-hiked around NZ. This explanation helps significantly to my knowledge of geology which inspires my desire to know and understand more. Please keep them coming. Have you done a session on the Lyttleton volcanic complex?
Thanks for the feedback. Sounds like a great memory. No, not done banks peninsula yet. So much to do so little time 🙂
I have skied on that mountain. The views are astoundingly beautiful!
They are for sure!
these are so interesting! thank you!
I'm very happy that you think so! Cheers!
Excellent. I love that land
Me too :-)
Awesome video! Since I live on an active volcano I have been fascinated by them! Especially how they 'record' the changes in the magnetic field!
Thanks for your comment - glad you like it
I love the content of these videos, thanks!
That's great, thanks!
Love the video! Great mahi Julian. 👍🏽
Cheers!
Awesome video, thank you
Thanks for your nice feedback 🙂
Thank you yet again!
Cheers!
Love your channel
Thanks, that's great 👍
Very informative and done in an engaging way, thanks for the vid.
Thank you for your nice comment
Really enjoyed your presentation and examples!
Thanks, I'm glad you did!
My beautiful memories, I stayed with couple settled near the summit village for couple of days and we climbed the summit, As we enjoy the views, aged man around 60s sprinted his way to summit and turned back sprinting all the way down to our disbelief. I always fall, injure going down the volcanic slopes. The region so beautiful and can never forget the warmth of the family who allowed us to stay there.
What a great memory!
very cool video
Thanks!
This series is so informative. Very well done.
Thank you
My favourite channel. I hope you guy grow. Absolutely fascinating content
Thanks! That's a really kind comment!
Great Video, thank you
Cheers!
Pretty scary when you think about the magnitude of violence involved in some of these events, like the one that decimated a forest so far away, a time-lapse of 20 million years would be epic, but even an animation would be interesting.

Thanks again
Very interesting and informative!
Thanks!
Explained in very simple terms, an excellent introduction 👍
Thank you!
Very interesting
Thanks Mike! Glad you like it
When I was a lad in the Fifties I had a poster advertising I think NAC. I found the aerial shot of Taranaki fascinating. It was the wonderful symmetry of the natural cone, augmented by the artificial circular boundary between the farmland and the natural forest, and between the cone and the plain surrounding it. Little did I know that, as explained so well here, the plain is mostly the mountain as well
Thanks, from an old Aucklander who has only visited the area once in a lifetime.
Thank you for your comment and your story
Very interesting video. Our geology in Ireland is mostly glacial deposits. We have rich metal deposits in our higher ground from gold to lithium. The north of Ireland has an abundance of sand and gravel. Our most prominent geological features are perfect U shaped glacial coastal valleys. Of course our most famous is the giant’s causeway. I do know that Ireland has one of the most diverse and different types of rock of any country in Europe. New zealand has far more interesting geological features than I realised.
Thanks for your interest and your comment
Any idea of the v.e.i.of the larger eruption?...such interesting content... regards
Well explained
Thank you!
Thankyou
You’re welcome 😊
This was damn awesome. I love your videos. I only wish I could rename and retag your videos so you get the tens or hundreds of thousands of views that you deserve.
You can always send me suggestions :-)
Muntahan gunung yang luar biasa, banyak batu besar
I lived under the mountain for 7 years it was great, we moved just far enough to still see it but its feels safer .
Maybe a good move!
It's all so amazing and young! No banded iron formations here, I think?
Thank you for the videos.

Thanks 🙂
@@OutThereLearning believe me, huge compliment, geology fan from across the ditch and share your work with US fans. So jelly of NZ geology, so much more exciting than Brisbane. Can’t follow the Normanby Fault above ground like you can with the Wellington Fault.
So you're Kathy who sent the blackboard duster?! I've really gotten into Nick's lectures this week. Super enertaining and makes the info stick. I was excited to come upon this channel for some local geology.

I don't see a lot of residents while the camera is rolling. New Zealand is an amazing country.
Excellent video what a tortured area you can only imagine the hell that must have rained down on that ancient forest.
Thanks and yes!
Geology is Awesome
Cheers to that!
Thankyou, for adding to my knowledge of Mt Taranaki.
A Freind, took me up from Stratford. The road was deceptive, as we thought, it relatively flat - until the engine began to labour.
We got to the snow line, & the alpine growth - the forest, on its flanks, is quite impressive, and so well 'watered', due to the exposed situation of the mountain.
Does the material, ejected from Mt Taranaki, have a high iron content, ? - it may go some way to explaining the black sand beaches, in the region
Yes, the black sand comes from Mount Taranaki and contains iron and titanium I believe. Glad you enjoyed your hike up the mountain
@@OutThereLearning the trip was by car, sorry to say, but none the less enjoyable. Both the driver & self, have 'disabilitys', which affect our mobility a lot - don't let it stop me getting out on local tracks.
Why didn't the wood rot after it was swept away 100,000 years ago?
Presumably by being buried in mainly anoxic conditions
How did the wood survive 100000 years? What a great info session,awesome!!! Must be because of oxygen starvation?
Yes it is! Because of rapid burial due to the deposition of volcanic materials derived from Taranaki, the wood has been removed to the surface environment where oxygen is freely available. Due to this, the wood has been subjected into an (not totally) anoxic environment that prevented it from being decomposed.
Has any of that wood been tested for carbon 14? It would be very interesting to see what it's reading is.
It will have had a statistically negligible reading which tells us that it is over 50,000 to 60,000 years old
@@OutThereLearning Thanks. Has the measurement been done? Is there a report about it that I can access?
gday,,, (04:17) area looks similar to seven sisters - malanda to atherton volcanic zone...
good vid thanks for upload...

Ex kiwi, have climbed this beautiful mountain several times, currently living in Kuranda near Atherton, moving to Tasmania soon

Looking at the shatted burried fragments of tree would suggest a violent event that happened relatively recently in NZ's timeline.
Called Mt Egmont before it was called Mt Tarakani.
Yes - Only recently exposed by erosion, but would have been ripped apart by the power of the debris flow.
I don’t want to nit-pick, but there seems to be a little confusion of vocabulary here, calling the hummocky terrain the result of a “lahar” or volcanic mudflow. “Hummocks” usually describe discrete pieces of a collapsed volcanic edifice that were transported like rafted islands in the midst of a larger avalanche and come to rest largely intact. “Lahars” are channelized flows of poorly sorted sediments mixed with water to move more like wet concrete. When Mt. St. Helens erupted in the USA in 1980 there were numerous processes occurring simultaneously: The over-steepened cone collapsed in a massive earthquake triggered landslide, the exposed magma body detonated in a huge lateral blast producing a Plinian column and pyroclastic flows, and melting glacial ice mixed with loose new and old material for form lahars in the existing river channels that traveled 10’s of kilometers to the Columbia River. Taranaki must have acted similarly producing a variety of deposits that just can’t be described in adequate detail in a 10-minute video. This is a great video taking the viewer all the way from the mountain to volcanic deposits at tidewater. Taranaki has re-built itself into a beautiful mountain, but the deposits in the ring plain tell us that in the future it will erupt again, and probably experience a devastating collapse again producing the whole panoply of volcanic collapse landforms and much human misery. Best to be in Sydney when that happens.
Thank you for your comment and insight
So Auckland cones Ive found have a similar layer stacking on cones ,is it the same system that makes them both,and Rangitoto being half under water does not allow us to see the base falling apart like Taranaki
average time for cone volume to end up in basin?
I wanted to know exactly what those sedimentary basins told us about the time scale? HOw many eruptions; how many collapses and their frequency over how long a time?
What kind of rock are those big grey boulders up the mountain that will evenually come rolling down and break up into smaller fragments, are they Rhyolite ???
Rhyolite is usually a whitish grey colour as it is largely silica. These boulders are mainly andesite lava
@@OutThereLearning Thank you

I wonder why it is no longer reffered to as Mt Egmont/Taranaki. To me it will always be Mt Egmont.
Mt Egmont actually
Thanks for the vid. (I'll keep writing these repetitive comments as I'm told it helps the utube algorithm when recommending vids.) I can write something different than "Thanks for the vid" I assure you, lol.
Thanks for watching and appreciating!
Hi Julian, be careful my friend. When you were higher up Taranaki it looked like some of those boulders were ready to launch. We hear terrible stories of volcanologists who have been caught out by nature, and nature and the laws of physics don't discriminate. Be safe my friend. Pete on the Isle of Wight.
Thanks Pete, yep you are quite right. You don't want to mess with that gully in bad weather or after winter snowfall for sure.
osssh i cant wait til i can afford a half decent pair of hiking boots..already lost 20 kgs in last 10 weeks and am lloking forward to get out hiking

Why should I have to pay for this video clip on UA-cam when this maunga is part of my family history
Who has asked you to pay anything?
Don't forget that it is also called Mt. Egmont by the great navigator James Cook.... please acknowledge that 200 year tradition that is not too different in time to the 7-800 year tradition by the peoples who first settled Taranaki.... both of which are miniscule compared to the geological age of the mountain itself - which can be measured in millions of years.
Indeed so. :-)
Much discussion about the name. My p.o.v. on that was long that it was either "Taranaki" or "Mt Egmont" not "Mt Taranaki" because "tara" means "peak" or summit. If that was the case then it makes no sense to name the province "taranaki" because only the peak is the peak and it is likewise redundant to call it "Mount Taranaki (mount - mountnaki). And in any case why mix languages in a name? If going for a Maori name then call it Maunga Taranaki. Better yet call it Pukehaupapa (which some say was the original Maori name, meaning "ice hill"). I therefore stuck with "Mt Egmont" even though I don't know or care who Egmont was and no doubt it would be possible to find something that gentleman said or wrote that would now be blocked by Twitter.
However those who favour Pukehaupapa also claim that "Taranaki" is also a name after a person, just like "Egmont", being named by one Rua Taranaki after his son Tahurangi climbed it. In that case "Tahurangi" would seem a better name.
In the meantime my recommendation is that locals refer to it as "the mountain".
Thank you for that helpful insight
I will suggest to only built MOBILE HOME in a 40 km radius of this huge instable volcano
Thanks!
An active volcano is not called dormant because its not erupting now. Please don't say its dormant.
Thank you for your comment. Good point
What is height of this mountain ⛰
We can calculate it's eruption time as it's very easy by some formula so we calculated the date and exactly that second at which it's eruption occurred very easily
2518 metres
@@whiteweta1465 it's sea level height ??

Never has been and never will be Mt egmont.

Yes, we need to care for sure!
Mt egmont
I guess its a beautiful mountain whatever we decide to call it :-)
Mount Egmont is the correct name and the name of our country is New Zealand !! 👍👍👍🌺🌺

ok boomer
Taranaki te Maunga!
Has gone by both names for decades. Taranaki is the original Maori name, Egmont the name given by Europeans in the 1800 ‘s
The mountain has had a Polynesian name since ages ago.end of story...
Imagine some dick coming along and renaming other great and ancient monuments of the world.it shouldn't happen, let alone be excepted.shame on you ignorant fools.🤘🏽
Thanks!... I prefer to call it Mt Egmont others can call it Mt Taranaki 👍🇳🇿
Mt Egmont,still is ,will always be.
Should have renamed it “Pukeonaki” since the Iwi preceded Mr Cook.
You're rusty, even in your mind...
@@xmj6830 Ha,Ha, Rust never sleeps ,Egmont as always ,and to add to that for more division It's always White on Top.
