Fears of the Yellowstone supervolcano erupting have cropped up from time to time, but a newly released study suggests that the hotspot may actually be waning.
No. The Yellowstone Caldera going off is an ELE straight up. The entire atmosphere will be gone along with instant forced realignment of all the continental shelves. There might be some microbes somewhere that live, but there will be no more humans.In theory couldn't a well stocked bunker in some other continent hold survivors for long enough? I have not read enough predictions about a Yellowstone eruption.
yes the planet and "life" would endure. thats really not saying much after the hundred or more years of a radiation cloud and maybe a few hundred thousand year ice age. there could be some fish chilling out under all that ice near a hot spring which could survive. but uh. thats it.Really go look at the super volcanos video I posted people it all there. Caldera eruptions linked to yellow stone hot spot happen roughly once every every million years are so. It is caused by a hotspot just like the Hawaiian one that made those island. As near as can be determined there is no indication that hotspots ever burnout. They are a near permanent factor like the contents and probably more permanent actually. Contents pass over them and they cause caldera eruptions on land and less violent eruptions at sea generally because of the thickness of crust.
It not the end of the world if one goes off. It would be the end the world as we currently see it. But life and planet will survive just as it has during the thousand are so previous caldera eruptions.
You're vastly overestimating the impact of such an eruption on a global scale. Yellowstone already has erupted in the past. In fact, in some cases so recently that humans were on the planet and larger mega eruptions when hominids were around. They've actually found geologic evidence of the ash zone. It literally covers like half the US and was over a meter thick hundreds of miles from the location. But keep in mind that it didn't cause any massive ELE of note. It's not like 90% of mammals or whatever went extinct.
Here's a historical context
When was the last time there was volcanism at Yellowstone?The most recent volcanic activity consisted of rhyolitic lava flows that erupted approximately 70,000 years ago. The largest of these flows formed the Pitchstone Plateau in southwestern Yellowstone National Park.www.usgs.gov
Sulfur does fuck up the atmosphere to be sure. In fact, that is partially why the non-avian dinosaur killing asteroid was so bad...it struck directly on a location that released a FUCKLOAD of sulfur and put it high into the atmosphere. My old paleontology professor also theorized that it may have struck in the Spring due to studies of plant fossils, because the super acid rain would have fucked up plants bad and because they used all their energy to emerge for Spring, they were less able to recover in the subsequent years (which in turn fucked up the food chain and why pretty much most land species weighing more than 50 lbs went extinct).
The Siberia Magmatraps are also theorized to have heavily caused the Permian-Triassic extinction, in conjunction with asteroid impacts. That extinct event was one of the worst in history...like 90% of all life died on the planet.
