That final quote says it all - Mother Nature just does not care. She will do what she does, & she always gets her way. An interesting point to note is the very probable CUMULATIVE affect of the decades-long activity of the Kuwae volcano. We tend to think of volcanic eruptions as short, sharp, isolated occurrences. In fact, many volcanoes around the world are almost continuously spewing gases & ash into the atmosphere. Consider Kilauea & Mt. Etna, just to name a couple, which have been emitting almost constant gases, ash & lava for decades. With the current uptick in volcanic activity the world over, literally 1000's of tons of SO2, CO2, & other gases are flooding the air of the planet. This is almost certainly contributing to climate change, along with all the noxious gases we humans pump out every day. I maintain it could take only ONE major catastrophe, such as a supervolcanic eruption or asteroid strike, to bring the planet to a tipping point. And we must remember - Mother Nature is VERY good at cleaning house.

A series of eruptions from 1420 onwards, leading up to the Big One in 1464 could explain the sequence of events.

It's also possible that the tectonic changes leading up to it triggered a number of smaller events from other active volcanoes.

[@gordonlawrence1448]

Actually we know what pretty much every single time. IE we can check ice cores for CO2 levels going back at least 300,000 years. Dendrochronology goes back around 14,000 years with a single year resolution. That pinpoints both the year and if it was a volcanic or not. There have been impacts more recently that are smaller then the Yukatan peninsula. Those are detected by one of three methods. If it's a metal asteroid then thinks like neodymium are detectable. if it's carbon then isotopes that are rare on earth spike. The same is true of Oxygen in water/ice impacts. That said the issue with knowing a volcano erupting caused something to happen in year abcd quite often leads to a mystery over which one and where. Was it a still active volcano that caused it? In that case with current science we have little chance as the evidence may be covered by hundreds of minor eruptions or just a few big ones or even both, If the volcano was underwater then it's a nightmare as we have accurately plotted so little of the sea floor. Radar mapping is reasonably accurate for shallow water but for water more than a few hundred feet deep the accuracy drops off to the point where it does not work at all.

[@dannykassmieh1198]

@@gordonlawrence1448 Knowing that something happened and pinpointing exactly what did it aren't the same thing. That's why events such as the "Little Ice Age" have multiple theories that attempt to explain the evidence they have, such as what you're referencing. I don't believe that science as a whole functions this way, but I do believe historical climate shifts are a good example of how science can determine what's more likely as having had happened instead of what did 100% happen. I think we all are aware of scientists who were 100% positive they were correct, only for that to change dramatically later on. :)

Good video! I like mysteries and drama involving natural disasters, like the tambora and krakatoa and vesuvius eruptions. But maybe this one was more than just this volcano? 1815 tambora eruption seems to have followed a mystery eruption around 1808 which was somewhat smaller but big enough so when tambora blew itself up there was still debris lingering in the atmosphere exacerbating tamboras effects. And the justinian plague era catastrophe seems to have been 2 eruptions around 535 and 540. So, maybe there was this one and another large one within a few years of each other?

[@here_we_go_again2571]

Some scientists have theorized that changes in climate (temperature) affects fleas and causes them to be vectors of plague (most of the time the fleas, as parasites, annoy ground dwelling rodents without infecting them with plague. If this occurs, linking earth temperature changes to outbreaks of disease would be a valuable contribution to our understaning. We already know that the climate, wild bird migrations and agricultural practices of southeastern Asia make that area the "homeland" of influenza.

Nice video as usual, I wonder if researchers have taken this any further forward since it was made, or if any of them have considered that by focusing on one event they may be missing something - could there have been several events in the Pacific that led to the ongoing issues - the ring of fire is very active, there are numerous large volcanoes we know of that are extremely active, and we also know that many have suffered flank collapse and sunk below the surface - there are also some very active and large volcanoes in South America straddling the equator - it is not difficult to imagine that over a period of 50-70 years we could see a number of very large eruptions that combined to have a global impact.

One striking characteristic of this event that sets it apart from most others is how rapidly the unseasonably cold summer of 1465 transitioned into an unseasonably warm winter of 1465-66. Only by throwing a combination of both SO2 and some greenhouse gas could a volcano cause such an abrupt change, and of course throwing large amounts of water vapor into the stratosphere is the most likely explanation here. So yes, that definitely points in the direction of something like Kuwae being the culprit, since we just saw recently how much water vapor Hunga Tonga-Hunga Ha’apai - a volcano with a similar tectonic underpinning - threw into the atmosphere.

I think the multiple eruption theory holds a great deal of sway especially as we know that relatively young volcano's can often be very active over shorter periods of time that older ones that may go milenia between great eruptions. On top of that, volcano such as Mt St Helens, a few in the Philippines and eve Hawaii, have shown the ability to rebuild a dome or fill a new caderawith cooled lava pretty quickly, in a little as a year. Who is to say that this dark age volcano only erupted twice but instead had a very active and long term eruptive phase. It could have well had a huge explosion near the earliest dates proposed and then had rebuilding eruptions which filled the caldera back in or built a new dome in a few as a couple of decades, and during that time subsequent to the first suspected eruption in the late 1430's, has a few large enough to at least cause atmospheric effects that cause the sun and sky to change color, leading up to another massive eruption some 3 decades after the first that added to the changes cause by the first eruption that were only just starting to allow things to become more near the previous normal.

I love that final quote. ✌🏽

[@amosbackstrom5366]

Can you do one on the eruption(s) of 536 AD? It was very similar to this except probably much worse.

[@eaf888]

Thank you

[@TheEvilCommenter]

Good video 👍

[@paulcochran1721]

What a feel good episode!

Great work! You're a wonderful presenter.

island volcanoes like Krakatoa or Hunga Tonga-Hunga Haʻapai with the magma chamber is close to surface and water forces contact by collaspe of side or massive faulting in the flank. The size of the explosion, and the amount of moisture that is pumped into the atmosphere is huge and dramatically changes weather for several years, due to the height this moisture elevated into the high stratoshere/lower mesosphere . short term heavy rains/flooding in the lattitudes close to eruption, eg Australia/Newzealand after Hunga Tonga. but latter the following year, effects will toll. massive snowfalls California, very little snow in europe, A weakening of the Polar Vortex which also effects weather pattern. Add in that the solar energy is coming back to a maximum and a strong maximum will shorten those effects. In 1457 the pattern of solar max-min would have been at a min and a very weak one if cycles are repeated backwards on the 11 yr cycle that is accepted. also the fact a 66yr cycle of high maxiums fade to a low maxium, 1457 would have been a double low which means the effects of any eruption would have taken a longer time to disperse back to normal levels. Hunga Tonga has been compared to Krakatoa, as it was the famously reported eruption due to the telegraph, but think on the scale of Thera/Santorini and how that effected history and use the science of hunga tonga, we might be able to appreciate the scale of climatic change suffered by bronze age civilizations.

I haven't found anything in Wikipedia about the epidemic of 1460s-70s, not even in the List of Epidemics. Strange. Someone should add it there.

[@Stettafire]

It's under the article of the second occurance of black death

I wonder if that could be what the Maori called Hawaiki? Their place of origin which if memory serves, sank under the sea some time after they migrated to New Zealand? Would make sense since the locations related to Zealandia the sunken continent that New Zealand is a part of in general.

You might also consider that the reason Pacific islands got inhabited in the first place was that people far over the horizon knew they were there because they'd seen smoke rising from a volcano at some point.

[@miacrowell1472]

This is a very good one

[@joanbrate]

Excellent... great videos.

There was a cartoon. I saw one where a person was talking to the Earth, and was like “I’ll save you!!” And the Earth basically said “I’ll be fine regardless. It’s *you* you need to worry about” Humans are so cute. We think that the universe revolves around us, but in reality we are just meaningless specs ☺️ for a perfectionist, sometimes that thought takes the pressure off

they (many of the same researchers) have pinpointed Krakatoa as the cause of issues in the 500s (536?) and that also triggered a plague... apparently certain pathogens are more active when temperatures are warmer or cooler, which changes the infection pattern, plus when the animals are hungry they invade human storehouses...

[@somestormchaseridjitwithwi2024]

A caldera is not an underwater crater. its a giant crater shaped formation after the magma chamber of a volcano rapidly empties, and the above volcano sinks into the magma chamber, leaving a depression in the earth. This can happen on land or underwater.

Rest in peace to those that passed away.

Yeah, that last quote strikes home to anyone not completely sold on mankinds "dominion" over nature. Our species exists on the precipice of extinction every day and Mother nature is totally indifferent to our fate.

Simon, I'm getting a headache watching the reflections of the overhead lights on your glasses frames. Perhaps you could place a sheet of fabric over them to diffuse the light as a single source?
