@4lyfesports It kinda sounds like the ejaculation process...

@therealKINDLE i dont think you understand, when the super volcano goes off it doesnt blow up in 1 single shot, there are multiple eruptions that occur until eventually all the lava is gone, with so much magma down there its almost impossible to go off in 1shot and btw yellow stone first eruption that was 2.4m years ago or something was suppose to be alot bigger than the one that happened 630,000 years ago.

4:30 "They come here to witness the power of the park's famous geezers"

It'd be funny if it showed a giant elderly person

Anyone with slightest sense of logic and knowledge of geology would instantly know that a so called "snowball earth" could have never happened. The carbon dioxide cycle would have and will prevent any such event. As water surfaces freeze and land is covered in snow, they stop absorbing CO2--50 million volcanic years worth of it, that accumulates in the atmosphere, creating a greenhouse that melts any freeze. Where else would all the volcanic CO2 and SO2 go if earth is frozen?

@15Positron I can't. It's as simple as that.

Yellowstone eruption of Lava Creek 630,000 years ago would have been so big that the whole planet Shook with rage as the it blew much of life out of existance. The Main explosive eruption would have been heard all across the Globe. It's like a Bomb as Big as Tokyo going Boom.

TOBA was THREE TIMES BIGGER. Making it possibly the largest explosive volcanic eruption within the last 25 million years. I can't imagine something that big, let alone 47!!!

[15Positron]

47 Supervolcanoes that is alot of supervolcanoes. Imagine all of them erupt at the same.

Oh my god - JUST like minecraft
