Muriwai near Auckland NZ is internationally famous for it's huge pillow lava flows and spectacular cooling columns. Geologist Bruce Hayward shows what they tell us about the biggest stratovolcano in New Zealand's geological history, the ancient Waitakare Volcano.

Iv'e been watching Nik Zentner and Shawn Willsey for some time and this video came up in my recommendation. So here I am. Those pillow lavas are huge. Love how you Geologists are so enthusiastic about what you do and it has sparked a new interest in me when I look out over my surroundings. Thanks.

We studied the Waitakere Volcano in high school, one of the hints the teacher gave us for our research was to "just google Bruce Hayward". They weren't wrong.

I still remember, as a kid, seeing the lava flows that were bisected by the Auckland motorway and seeing so many volcanoes. Enjoying your talks. Thanks

love this outcrop, it was the 1st pillow lava I saw as a geology student in the late 80’s. thanks for making this video Bruce. Just want to mention that there are also really beautiful feeder tubes exposed at Hjálparfoss in South Iceland, near Búrfell hydro power station.

Thanks so much for that information. I missed that when I was in Iceland and it is the closest example I have seen anywhere to what we have at Muriwai.

Great video! Cool geology there and a lovely beach too! It's a real pity that the Waitakere Volcano has eroded away so much, leaving just a small remnant of itself behind. It must have been truly spectacular when it was active.

Second largest pillow formation in the world (somewhere in South America?) and probably the most accessible. Anywhere else on the planet and there would be an interpretive centre and a charge to see them, and they would be fully protected.

Was there a giant volcano out there somewhere ,iv surfed out there a bit and we would always look at these crazy formations of lava ,i was working on the Motorway thrugh Mt Roskill area sorta had the same looking lava,man the amount of hollow lava tubes was scary,the other crew lost a rather large compactor down one of the tubes and it was so far down they couldnt get it out lol it was like a rabbit warren the amount of lava tubes out there

@PaulG.x 3 месяца назад

The volcano rose from between 3,000 and 4,000 metres above the sea floor, so the peak was around 2000 metres above sea level. In comparison the highest peak in today's Waitākere Range is 474 metres .

@Julian_Wang-pai 4 месяца назад

Were the deep oceanic conditions (extreme pressure and freezing ocean at depth) conducive for the formation of such extraordinary pillow dimensions?

@OutThereLearning 4 месяца назад

Good question - not sure of the answer though..

@PaulG.x 3 месяца назад

@@OutThereLearning The cooling of the lava may have been faster and more effective because the high pressure would have kept the water from boiling until it was raised to a much higher temperature. The same effect is used in a pressurised cooling system in an engine.

@sixthsenseamelia4695 4 месяца назад

Thank you for the tour! Definitely putting this on the "To Do" list next time I'm in Auckland. Would really like to see the lava tubes in Mt Roskil that another commenter mentioned. Hypothetical question; where do you think would be the most likely place for a volcano to erupt in the Auckland volcanic field region?

@OutThereLearning 4 месяца назад

Not sure if anyone knows the answer to that. Rangitoto was the most recent eruption, but maybe there is a geo out there with an opinion on where next? It's definitely something that scientists and many others would like to know!

@brownstone12345 4 месяца назад

Great video. I take all my international visitors to see the Pillow Lava formations at Muriwai. At one time I had read that this was only one of two such that could be seen on land, but I think that is not true since I've seen videos of others. Could you please clarify? Thanks.

@BruceHayward1 Месяц назад

Only similar rocks like this I know of are in Iceland.

@MeppyMan 4 месяца назад

Amazing. Thank you. Incredible what you can miss when you don’t know what you’re looking at. Would that part of the ancient sea floor have raised up to where it is now, or is it all just due to the ocean receding due over that time? (Or both?)

@OutThereLearning 4 месяца назад

Thanks for your question. The ocean floor has been uplifted, but in the meantime the bulk of the volcano has been eroded down.

@daleolson3506 4 месяца назад
