Taupo Supervolcano Update; Alert Level Raised for the First Time, Earthquake Swarm
Рет қаралды 230,629
Күн бұрынIn New Zealand, the supervolcano known as Lake Taupo to the south of the city of Taupo just had its alert level raised for the first time on record. This change was made in response to a series of several hundred earthquakes and volcanic uplift which has been detected in the eastern section of the lake, meaning that magma and hydrothermal fluids are on the move. Although these swarms are not as energetic as previous episodes of unrest, they are related to the movement of magma at depth. This video will discuss the implications of this earthquake swarm, and how common periods of seismic unrest are at this supervolcano.

I have a few points to note about this video. 1. The alert level was raised on September 20th, NOT August 20th (made a minor mistake in this video). 2. Sorry for the really late upload. I rewrote this video several times and created more graphics so that my work would be far less likely to get misinterpreted. 3. I would not worry about Taupo's latest unrest; at least for now. Large caldera systems such as Campi Flegrei and Yellowstone also produce semi frequent (from a geologic perspective) episodes of unrest. 4. There has been a recent discussion about whether or not "supervolcano" is a real scientific term. I am of the opinion it is, for volcanoes which either have produced explosive eruptions with >1,000 km^3 tephra and possibly for volcanoes which have produced large VEI 7 eruptions but have the capability to produce a VEI 8 event. Just because tabloids have misused the invented term does not mean it isn't a real word. 5. Sorry for my potential buthering of the word "Taupo". I have trouble saying it correctly for an unknown reason. I was trying to pronounce it like "tow" as in "towel" and then "paw". "Tow-paw".

Kiwis of European extraction seem to pronounce it like toe-poe. But with some slightly odd diphthongs that we don't have in American English. Would be curious to hear how indigenous folk there pronounce it. I suppose it bears repeating that the next eruption at Taupo is more likely to be relatively small, rather than a monster, right?

I wonder if/where there is a highest risk of a small explosive eruption (I'd imagine a maar is most likely). Taupo is a pretty crazy volcano, even though the risk of large eruption is quite negligible its still impressive that in a mere 20 thousand years it produced a VEI 7 after its massive VEI 8. Going more in depth to the various TVZ volcanoes would be neat, like the various incredibly obscure calderas to the north, of which Okataina presents a serious threat.

I was skiing on Ruapehu as a teenager in September 1995, when it erupted at the end of the day, just as we were about to head down the mountain, I'll never forget watching the huge rooster tails of black ash and mud shooting out of the crater against the clear blue sky!

Sorry, I accidental.y pubished my comment while I was still typing. The Whakamaru Ignimbrite erupted some 2,000 cubic kilomters of volcanic products, while the Oruanui eruption erupted 1,170 cubic kilometers of material. Now, 12 caldera-forming eruptions have occured in the same time period, Including the Hatepe eruption, The Nakum eruption ( Might be wrong on the eruption’s name, produced the Okataina caldera. ) and much more. The Taupo Volcanic Zone has produced numerous VEI 5 + eruptions. The volcanic zone also seems to erupt exceptionally violently when gas-charged, like the Hatepe eruption, which covered 20,000 square kilometers in Ignimbrite. Both the Taupo supervolcano and Taupo volcanic zone are truly fascinating geologic features !

Pretty unscientific nonsense. The level of the lake isn't at an abnormally high level, I mean the level is set by the control gates on the Waikato for goodness sake for hydroelectric generation in the various dams down stream. Meaning the lake level is pretty stable all year round except in extreme dry conditions. Also as pointed out in the video, parts of the lake bed is RISING. If the weight of lake water is the cause, shouldn't it be doing the opposite. Given the size and depth of the volcanic system which lies below the lake, the surface hydrology has virtually no influence on how it operates.

Let us hope if it ever goes off again, it is just a quiet little eruption that will just create a new island in the lake. With millions of tonnes of water in the lake, there is a scary chance that it could eventually go like the Tonga volcano. The whole north island would be affected. Very unlikely, but still, there is essentially an ocean sitting in that caldera.
@user-uy6uc5ey5q Жыл бұрын
Lake Taupo hold about 59 km3 of water, which isn't small on a human scale but isn't anywhere anything like an ocean. The smallest, the Arctic (only holding 1.3% of the earths water) holds18.07 × 10 to the power of 6 km3. The mechanics of the magma chamber beneath the lake wont act how you imagine and an island is very unlikely to be created. Whats likely to be causing the localised lake bed rise is trapped superheated gases/steam, this will either slowly release into the lake or you could have localised steam eruption similar to what happened on White island a few ago. This obviously can be very dangerous to people in the immediate area, but is nothing like the scale you theorise
@SaoGage Жыл бұрын
I think some laypeople have a misconception (thanks media) that supervolcanoes only “super”erupt, but of course that’s not the case. Most of Taupo’s eruptions are within VEI 3-5 punctuated by increasingly infrequent 6-7-8’s. If Taupo’s magma chamber were about to supererupt, we would damn sure know about it. That’s an enormous amount of active heat and material down there, and it would register on the surface. If Taupo does go off in the near geologic future it’s probably going to be a vent on the reefs and be a 3-4. I think with respect to Taupo doing a 6-7 size event, the question becomes how much the system recharged after Oruanui (VEI 8 27kya) relative to what it discharged in Hatepe (VEI 7 2kya) and its other relatively recent > 4 events. Maybe it could throw another 5-6 sometime in the relatively near future, but again the activity leading up to it would be detectable. And the activity we’re seeing now isn’t suggestive of such an event.

Likely the same as it normally would affect volcanoes, since that process is typically how volcanoes form. Though if I had to hazard a guess, and take my words with a planet-sized grain of salt as I have no intricate knowledge of Volcanology or Geology, it likely would result in more frequent lava emissions (VEI 0-1, maybe 2) from cinder cones, spatter cones, and rifts.

Very few, Campi Flegrei and Taupo, 3 if you count Rinjani (Samalas). But it's regular business, large calderas have cycles of unrest, even with insane ground deformation, no eruption can occur so i wouldn't bother much. Also worth noticing the level 1 doesn't say much, level 1 qualifies as any volcano that has a sudden spike in activity, other supervolcanoes are also recharging for next eruptions, the difference is that their activity has not lead to spikes in activity in recent history like that.

Both to answer you question. There is both in the chamber and when the liquid ratio goes higher and releases gasses from the freshly melted rock, that is the fuel for the expansion and upward movement of magma fluids through the volcanic conduit system and if the melt and the uplift is strong enough to reach the surface you have an eruption. The ones that don't make it harden into dykes.

It'd suck for the locals, but it wouldn't be the end of the world, we can handle the aftermath. If it were gearing up for a VEI 7-8, I'm sure we would know far in advance. There'd be a lot more seismic activity for one thing, so much hydrothermal energy that Wairakei would have to shut down, and that isn't mentioning the ungodly amount of ground deformation that even the lay would be able to see without geological equipment.

@@curiousworld7912 There is a town in Arkansas called Hot Springs appropriately named also for hot spring baths people can enjoy. There is also a crystal mine in the area which common for tourists. The Madrid fault zone is thought to be a called rift that could have split the country in two. It is still geologically active as the two massive quakes about 1810-11 indicate. They were in the 7.8--8.1 range. This rift opened up earth enough millions of years ago to allow magma to be present warming ground water for the hot springs.

@Charles Richter Thank you. I appreciate your help in this. It's just something that I've occasionally wondered; why it is we have hot springs, and had a major earthquake, in the middle of a tectonic plate, or if the two had anything to do with each other. I didn't think it was a 'hot zone', such as Hawaii, but I thought I'd ask people here, who understand far more than I how all this works. :)

In polynesian languages, the 'ng' is pronounced as it would be in "doing". Tonga is also pronounced this way, yet everyone else on earth says 'ton-ga'. Also, Taupo is pronounced 'Toe-Paw'. Many new zealanders get this wrong, as it never used to be pronounced this way until respect of the maori language has been pushed by the government
@mapledoctor3915 Жыл бұрын
As someone who has taken a course on te reo at university in NZ from a Māori lecturer, Taupō is not pronounced “toe-paw”, that is a misconception. The ‘a’ is pronounced as in ‘bar’ and the ‘u’ is pronounced as in ‘put’. When these sounds are said quickly in conjunction, they make an “ow” sound as in “how” (try it yourself). So it is pronounced “tow-paw”, ‘tow’ as in ‘towel’. It is a common pattern I see for people here to claim an incorrect pronunciation is the correct way, and then call out people who don’t say it that incorrect way as being wrong.

Those are very specific dates. I would imagine that it would be possible to estimate the dates they erupted, but not to be able to be that specific.
