    It might seem like I am nondecisive in this video, but this owes to the fact that I can't truly rule out any of the 4 possible eruption scenarios. The large amount of magma present is quite worrying, and combined with the cracks that formed near several population centers in 2018, I wanted to cover all possibilities. As a final thought, there is a highly unlikely but theoretically possible 5th scenario; a basaltic plinian eruption. This scenario would become more likely if an explosive eruption began at Lewolembwi and then unexpectedly escalated. ~0.5 km^3 of magma is sufficient to generate a large VEI 4 eruption, although this scenario is still quite unlikely.

      hey do you think you can make a video on the asteroid crater in antartica that has a diameter of 500km because i heard you talk about it in your siberian traps flood basalt eruption video and i was wondering if you could make a video explaining the asteroid crater and wonder how large was the asteroid that formed it and how many tons of tnt was the explosion from it as well as how much devistation it caused in a certain radius like, how far away from the impact site ignited into flames and how far away were trees and plant-life were flattened by the shockwave cause i really want to know about it.
      by the way the asteroid crater is called the wilkes land anomaly due to the fact we don't know what caused it but we theorized that it was caused by a giant asteroid.
      and i also want to add a question here: if the asteroid that killed the dinosaurs caused an earthquake with a magnitude between 10.3 and 13.0 on the richter scale, then how big was the earthquake from the wilkes land asteroid?
      i know it's a little weird but i'm curious and want to know everything about the asteoroid that cause the 500km wide crater and the siberian traps eruption on the other side of the world.
      i hope this gets a reply sooner or later

      The same dangers apply whether roads are paved, dirt, animal trails, or nonexistent. You can stay on the eastern half of the island, just I’d stay away from the older maars and cracks which formed in 2018. Ambrym is one of the planet’s most scenic volcanoes, and those in my audience who visited greatly enjoyed it. Yes there isn’t much infrastructure, but to be honest many nations with highly active volcanoes are like this.

    This seems a _lot_ like Leilani Estates 2.0, its even on an eastern rift zone. Rift zones on highly active volcanoes have gotta be one of the _worst_ possible places to build. Seems people near Nyiragongo, Kilauea, Mauna Loa, and Ambrym are all guilty of this mistake (although the ones in Hawaii are far more egregious considering those were built in a country with the resources to know just how bad it was). Hopefully this turns out to be nothing.

    • @michaeldeierhoi4096
      @michaeldeierhoi4096 2 ปีที่แล้ว +5

      A quick Google search reveals several possible means to date a volcanic eruption. The most accurate is if a tree that died in the lava flow then the tree rings can be analysed and correlated with other trees in the area in a field of study called dendrochronology. The tree can also be carbon dated to get a fairly accurate date.
      If there are trees killed by the eruption that certain radioactive isotopes in the lave can be used to determine a date. The potassium/argon relationship is often used in dating volcanic eruptions and can also date material that is in excess of the maximum age the carbon dating is effective which 50,000 years.

      @@MikeLisanke I am always glad to see that someone is interested in knowing more about volcanoes. I have been interested in volcanoes and geology especially since living in New Mexico for quite a few years. We have about every kind of volcano there is here though nothing has erupted in a few thousand years. Here's a few responses to some of what you are asking.
      As I said in the last comment some volcanoes are dated by radioactive isotopes like potassium/argon that are too ancient to be dated by Carbon 14. C14 requires organic material anyway.
      I'm not aware of a database for volcanoes although the next best thing are volcano observatories such as one in Alaska that monitors volcanoes there. And there are others around the earth.
      As far as volcanoes not yet studied yet, this list would likely include almost exclusively submarine volcanoes which are countless in number. Also there probably some volcanoes in remote areas such as in the Andes Mountains that haven't erupted for a long time and are considered extinct. One such volcano in southern Chile hadn't erupted in 9000 years then suddenly did so some 10 or 12 years ago. You can bet that surprised a lot of volcanologists!
      Other volcanoes do surprise researchers at times because of uncharacteristic behavior. More recently Honga Tunga Honga Ha'apai surprised everyone by its violent eruption. Research on volcanoes is constantly evolving and learning something new.

      You seem to think volcanos only add elevation to land mass. You are ignoring events such as Hunga Ha'apai where large undersea calderas are formed and fill with sea water.
      Sea level rise the past two centuries or so is mostly driven by the expansion of sea water as it warms. Add to that some glacial melt. Both are the results of us humans changing the atmosphere and land surface.
      If you still don't want to believe that... well what can convince you? If you think sea level is rising due to volcanos, ask yourself how long volcanos have been on this planet, and why for several thousand years before 1800 sea level rose on average of ~1mm/yr, while since the modern age sea level rise has accelerated to ~3mm/yr and in the recent two decades is even a bit more than that.
