How much of the next to nothing that solar power provides will be lost when Yellowstone National park erupts and blacks out the sun for years?

Yellowstone National Park (USA) sits square on top of a massive hotspot in the Earth's crust. It is a "supervolcano" that erupts every 600,000 to 800,000 years or so. The last eruption was 640,000 years ago, so we're due any time now. The land around Yellowstone is actually "bubbling up" right now as the magma chamber swells underground. An eruption of the Yellowstone supervolcano 2.1 million years ago produced 2500 times as much ash as the Mt St Helen's in 1980. My guess is not much solar power will be generated until the skies clear from that blast. But considering the utter devestation it will bring to at least the central mass of North America, sunlight getting to the crops might be a bigger concern.

Ahh thanks for the explanation houston, I couldn’t make sense of it at all... “It is a "supervolcano" that erupts every 600,000 to 800,000 years or so. The last eruption was 640,000 years ago, so we're due any time now.” That being so, "any time soon" could be anything between one hour and 160,000 years..! Not going to hold my breath on this one.

There are 6 super volcanoes around the world. Three of the Six happen to be in the Western U.S., Wyoming (Yellowstone), California and New Mexico, while the other three are on the other side of the Pacific Rim in New Zealand, Sumatra and Japan. Having said that I am with SMW on this situation. Reply #6. Sep 11 11, 7:28 AM |

I've checked up the little information that is available on the Yellowstone caldera, and although it still heats the water and surface by a good number of degrees, the experts seem to believe the depth of the channels are way too far down to blow, there is too much rock above them. So while it remains an active system and may have individual eruptions at any time I think all the concerns about the whole lot going up aren't based on the total information available. Even if it was possible there aren't many warnings for eruptions and still may not happen for centuries if it could. I'd also guess the authorities are well aware of this or they'd be evacuating the area for miles around, that tells me all I need to really. Reply #7. Sep 11 11, 6:18 PM |
