[@dongargon763]

There is another really big tree mould near that spot, probably a kauri it has a grill over so people don’t fall into it ,it’s on a great short coastal walk from Milford beach to Takapuna beach with lots of interesting geology ,go at mid to low tide .

[@annwatchman6885]

Excellent vid. Thanks for your clear explanation of Auckland's volcanoes 😀

[@priscillacook6742]

I remember learning about our volcanoes when I was in College but the volcano that concerns me is the one in Taupo, apparently it’s active and is a Super Volcano!!!

[@zimbomah12]

It was the most recent super volcano to erupt. Saying that, that was 26 thousand years ago......

[@freespiritable]

You'll learn from Yellowstone how to deal with that

[@pyromaniac354]

Look at the size of the lake which is a crater lake,its friggin huge

[@gaius_enceladus]

@@zimbomah12 - The eruption 26,000 years ago was the Oruanui eruption - en.wikipedia.org/wiki/Oruanui_eruption The most *recent* eruption of Taupo was the Hatepe eruption about 1,800 years ago - en.wikipedia.org/wiki/Hatepe_eruption

[@joannahodge9077]

Great video, thanks for publishing. I remember these Auckland geology field trips when I studied at the University in Auckland in the early 90's. Would love it though if GNS could add closed captions to your videos, thereby making them accessible to everyone who wants to learn more about geology in New Zealand. Thanks.

[@GNSscience]

Thanks Joanna, you are right - we have a bit of catching up to do with the CCs. Might take us a while with other things going on, but will get there eventually! Thanks for the reminder!

[@joannahodge9077]

GNS you rock! Thanks for the CC on this and your new Rotomohana eruption video. I teach geology in Canada and represent Natural Resources faculty on our Accessibility for Academics team, and I really appreciate the effort you have put into accurate closed captions on these videos. Awesome. Keep up the good work.

[@angelaxu110]

What a great video! Thank you, Sir! I learned a lot about volcanoes! 🌋

[@kansasthunderman1]

You might want to search for videos of the Kilauea Volcano in 2018. There are at east 10 hours of exciting videos about the earth's most active volcano located on the big island of Hawaii.

[@jamie_edwards7090]

[@tgchism]

Very well explained!

[@LIZZIE-lizzie]

Would it be safe to say if a volcano blew of any magnitude, New Zealand would be wiped out? Scary stuff

[@kansasthunderman1]

Most volcanoes affect a relatively small area and New Zealand would not be damaged.

[@karlashdown5228]

i remember at school on the North shore being told that Onepoto & Pupuke are connected by tunnels formed when giant Kauri forests got felled by an eruption & after the tree's rotted away underground waters started getting through & wore away at these passages so that the cave system runs all around this area having lived in this area most of my life & growing up around the hills's of Devonport & the beaches it doesn't sound at all far fetched in fact it made some sense to me at least.

[@tobyglyn]

A fascinating video, thank you!

[@davidboyd8113]

Lake Taupo is the second largest Caldera in the world next to Yellowstone National Park and I believe the Taupo lake is heating up so it won’t be long before Auckland goes up in smoke what an intelligent place to put New Zealand’s biggest city

[@Tony_Malini]

Zk AY 🤣

[@LIZZIE-lizzie]

@ David Boyd No different than San Francisco. After their huge quake in 1906, if not mistaken, city politicians, planners, and builders built San Francisco right back up where it was taken out. Really, it is only by the grace of God San Francisco hasn't had an earthquake! The politicians, etc., could give a fork about an earthquake in San Francisco. If they die, well, that's that. If not, they stand to make billions as individuals, if not more. They KNOW California is Ground Zero, "they" are purposely burning out SONOMA COUNTY in Northern California, the amount of homeless and human waste/filth on the streets are a purposeful byproduct of what WILL happen in the future. They expect everyone and everything to be taken out, buried alive and no hope for any hope. They are disgusting examples of humanity.

[@davidboyd8113]

[@maritasue5067]

KZbin sent me. That’s perhaps because I’ve been looking up the “Boring Volcanic Field”, much of which is within the city limits of Portland, Oregon, USA. Many of Portland’s parks are located on these cones and, luckily for Portlanders, the last eruption was 57,000 years ago. They have more to worry about with the larger Cascade volcanoes, like Mt St Helens and Mt Hood.

[@izwanshaari9854]

Those who now live in Auckland are badass 💪💪💪

[@wlhgmk]

Could White Island do a 'Krakatoa". That is to say, blow enough of it's top off to let the sea water in to the guts of the volcano, resulting in a Krakatoa like explosion.

[@kansasthunderman1]

Any volcano can explode of water enters the vent and mixes with the magma. The surface extent of the explosion depends on the depth below the entrance and the structure of the volcano. Strato Volcanoes are built up of loose material that will fragment during an explosion and scatter debris for miles. The shock wave from the blast can also propagate 1000s of miles.

[@OutThereLearning]

Fantastic geology

[@muzikhed]

Yes I totally agree. Glad to see you here. Hope you will soon make some of your excellent videos yourselves of the Auckland and Northland areas.

[@MrWombatty]

My understanding was that Auckland had moved on & was no longer over the magma hot-spot!

[@GNSscience]

Not so!

[@MrWombatty]

@@GNSscience Okay, so how old are the volcanoes in the Auckland area, & which ones would've been the most recent?

[@hudsonquay]

@@MrWombatty Rangitoto Island was estimated to have been formed by an eruption approximately 600 years ago, which is 2 minutes ago in geological terms.

[@prosodiclearning]

Fishful winking

[@brucehowe194]

What's to stop the dormant volcanoes in erupting again just like the one in Iceland 🇮🇸 recently.???

[@jackgibbons6013]

The hot spot moves around the field. The next eruption would likely be a new volcano. There’s no real reason an existing one has to be the place it comes through. I believe the middle of the harbour is the most likely next location. But there is nothing stopping another eruption. Will happen again sooner or later. Luckily the yearly or even decadely likelihood of an eruption is very low. Over 1000s of years though it’s inevitable.

[@BruceHayward1]

After each volcano erupts, the magma cools and solidifies in the plumbing beneath it and so next time magma rises towards the surface it will deviate off up an easier path once it reaches the blocked plumbing and so each eruption makes a new vent and new volcano.

[@scatlar2]

who remembers the volcano simulation at Auckland muesem tho

[@quickaccessdeliverynsw5400]

[@Mark_Dyer1]

Reminds me of the landscape of the Auvergne, in France. There are also presto-magmatic explosions present in the Eiffel District of Germany. The great Benedictine Abbey of Maria Laach, in on the shore of the Lachersee; one of these crater-lakes. Who know when Mother Earth will next remind us, who's boss?

[@mickcarson8504]

When they first built this settlement, nobody thought that they were building a city on a time bomb. Most cities are. It's like Italy. The entire Apennine mountains line from north to south were made of spent and dormant volcanoes. It's a fact that Italy's entire shape was once a volcanic crack on the face of earth billion year ago. They were probably giant volcanic uplift that, over the billion years of weathering of rock face has resulted in erosion that became the surrounding plains and valley of fertile soil spreading towards the sea by the action of rain ancient rivers criss-crossing from mountains to sea. Today's Apennine mountains are the older remnants of the giants uplift of the entire Italian penninsula, because of the weather's action from wind and rain. Whereas, up north Italy, those mountains of solid rocks would have been younger than the south counterparts, as they kept pushing up and when the 'plug' was finally covered by their might weight, the inability of the lava pushing all that weight finally ended, and the Alps are the snow capped mountains remaining today, with Mont Blanc (Monte Bianco) being the highest of them at 4,808 m above sea level, plus/less 8 m difference, due to tidal changes. Mont Blanc is not a volcanic core but a gigantic piece of solid rock uplifted by the force on Nature. To us, it looks gigantic, but to Nature, it's just a scratch in the rock crust. Uplifted rock plates usually end up fully vertical or semi vertical caused by the force of lava during the billion years development after this planet became spent from a violent and fiery star to what it is today, a balanced and more calm planet. All planets eventually start as a melting ball like the sun and gradually exhaust themselves of their every and die out, eventually, but not in a day, or years, millions of years at least. Jupiter is at that stake, but it is too far from the sun to provide light and heat, so the cloud we see on Jupiter are similar to those on earth when temperatures are mixed and the weather violently turns into cyclonic force causing thunderstorms and hurricanes, freezing cold and snow or floods.

[@freespiritable]

Thank you, i live right above the opposite side of the crazy tectonic plate that formed and is shaping Italy. It is so calming to know the danger above which i am living. Especially now that the plate has gone super active and is triggering hundreds of quakes everyday under our feet. 😥😬😓😢

[@mickcarson8504]

@@freespiritable I went to Italy in 1980 during a three months school excursion to learn about Italy's way of life and their language, then in January 1981 we would proceed to Germany, Poland, France for the purpose of seeing and styludying the changes after WW2. It was unfortunate that we planned to remain in Italy through the new year of 1981. The excursion team had split in Rome and each group went to different location of Italy. I and my Italian friend had traveled to Lioni in early November to visit his relatives and to witness a white Christmas in coming December. He had relatives in Lioni and an uncle in Teora. We were welcome to stay with his relatives in Lioni and had on 2 occasion gone to Teora to meet and stay with his uncle before we returned to Lioni on the 20th November to be with the relatives, 2 sisters of my friend's father. After a walk in town, visiting the local shops and men decorating this giant pine tree for Christmas, we retired for dinner. Everything seemed peaceful sitting by the fire in front the large mantlepiece when just after 6pm we felt a tremor and panicked somehow at the strange feeling at the surrounding movement inside the house. But my friend's auntie and uncle, having had some experience in the past with earthquakes as kids themselves were aware of what might happen next. She and husband quickly ordered to everyone inside to grab heavy clothing, coats, shoes, hats umbrellas, etc., and immediately rush out the door and into the wide open street, for they kept saying to hurry because a stronger earthquake could follow next. We grabbed what we could to stay warm and bolted out the door in no time. My friend and I took the entire small suitcases which had some winter clothing, school stuff, passport and photos taken in the month we had been in Italy. No idea where the others from the team were in Italy but we were to return at the airport hotel on the 20th February 1981 to board and return to Melbourne. So, while we rushed out and into the street we saw all others rushing out into the street, black dressed sihoulettes under the street lamps accumulating at spots in the street that were wide enough to avoid being hit by falling buildings, some were in pyjamas being helped to dress warm. Women were shouting, kids were crying or screaming, it was an unreal scene. For about 20 minutes people waited and braced for the worst but it seemed an eternity that nothing had happened yet, everything seemed so quiet with some people trying to go back in their homes to grab something to eat or extra clothing for the night, until at about 6.40pm yells and screams were waved towards our end as the earthquake started from light shake followed by a violent thunder and raising of land, tilting of house, rock material from buildings rumble breaking and falling down, people caught under, dogs running for their lives, animals, sheep, donkey and cows bolting off in panic and running right into falling buildings, the dust from the rumble was blinding. It was like the end of the world, nowhere to run for cover. Those who hid in the cellars were entombed but not dead. Some cellars were flooded by tap water, gas leaks in some mansions also poisoned many. Others simply exploded. You couldn't tell the difference between WW2 and this earthquake. In about 20 minutes of mayhem the dust cleared by the light breeze and then silence, hardly anyone could see the state of destruction, fire, sewerage smell, burned bodies smell, no street lights, powerlines erected from buildings collapsed and people walked straight into them, getting electrocuted. After the calm people even tried to save those buried under the fallen buildings. Hardy anything could be seen in pitch black, most people were covered in dust. And that was not all. Three more aftershock came soon after the main one, about 30 minute apart in succession waves, the last was faint enough to have dislodged some lose rocks or caused additional rumbles. Homes in Italian towns or villages were made of rocks shaped into large bricks and cement looked like cheap Lime and sand. Most homes are probably more than a thousand year old. We slept out in the open and so did all other people. You could hear calls for help from those buried under the rumble but saving them by removing debris meant that the other half of the standing buildings would topple down and kill them as well. Daylight came quickly enough to see the destroyed town of Lioni, much to the distress and wailing of women and crying kids with tears caked in dust. I have see Berlin destroyed in WW2 but I have never seen to what extent an earthquake can destroy. At least in war you get bomb craters, etc., but an earthquake can open the ground and eat you alive, or spew out lava that is far worse than Pompeii.
