I've was told that there were only 2 or 3 places on the planet similar to the Yellowstone park supervolcano>> or am I operating on bad information?Ankerson wrote: ↑Sat Dec 07, 2019 9:23 amJoe,The Mastiff wrote: ↑Sat Dec 07, 2019 6:02 amYep. All they can do is watch the seismometers to see if they can detect movement of magma heading up. It's pretty new stuff so it's possible they might not see what they think they are seeing and learn something too late.
There are other supervolcanos. IIRC, mono lake in CA has one ? Naples in Italy has Phlegraean Fields caldera.https://en.wikipedia.org/wiki/Phlegraean_Fields There are more and they all pose some danger.
I found in my readings that there have been substantial eruptions in Yellowstone that were not the whole supervolcano thing that ate a whole mountain range. I'm not sure how often they happen and at what point they themselves can trigger a full scale event. Supposedly one happened in or next to Yellowstone lake but that sort of thing is difficult to research online as everything vulcanism related about Yellowstone is about the big one.
There have even been questions raised about an enemy nation of the US attempting to trigger an eruption with a nuke or even more likely with "rods from god" ( tungsten telephone pole sized weapons dropped from high orbit that will have so much kinetic energy from pure speed they can reach depths of a half mile ) used to unzip the earth causing a tearing and release of magma which would spread to a maximum eruption.
There are like 40 total with something like 14 active I believe.
One thing positive about Yellowstone is that there are vents omitting steam and pressure all over that park. There would have to be pressure beyond belief to make that whole system to erupt I've been told as well?
Also I've heard recently that there are 93 active volcanos in the continent of Antarctica>> but yet there is hardly anything at all said about those.
I'm just saying that all I know about volcanos or seismic zones is what I've been told.
Yellowstone is inside the crater of the Super Volcano.
They said 40 total and like 14 active with only 4 like Yellowstone.
