finally, i can put my gcse in geography to use
okay, so first off, this isn't how ash would act during a super volcanic eruption; allow me to go over what would happen during a super volcanic eruption:
- the eruption would render anything inside and on the outskirts of the park 50 shades of fucked
- the mushroom plume of ash would be so large that light dustings of as would reach florida
- it's likely that areas within a 500 mile circle of the eruption point could be covered in up to 10 centimeters of ash (more on that later)
- due to the eruption, midwest american agriculture would, for a short while, be turned to dog shit, and rivers and streams in america would be filled with grey muck leading to the death of wildlife and possible extinction of some species
- the sulfur dioxide released from the volcano, which for reasons i can't remember becomes sulfur aerosol, would become part of the atmosphere and reflect part of the heat coming from the sun away from the planet, thus causing a worldwide climate change/drop that could last up to a decade
- this will lead to some shortages of food/some changes in the world's eco system due to the drop in temperature, but if i'm not mistaken i remember the drop in temperature being a minimum of 4 degrees celsius and 10 degrees celsius, i did my gcse a while ago
-as the mushroom cloud of ash dissipates and falls, places as far as washing dc and new york will get between 1 - 10 mm of ash
super volcanoes are often over exaggerated in the damage and problems they can cause. there are much worse possibilities and natural disasters that could occur that could lead to a lot more problems - although, it'd still lead to a LOT of issues, and it'd be catastrophic.
one of, if not the biggest problem, caused by super vocanic eruptions is the ash. ash would lead to the death in crop growth, animals, and people. if i'm not mistaken i remember ash weighs like 4x as much as wet snow - now, picture ten centimeters of that on an unsturdy roof. it'd lead to millions of not billons of dollars in property damage and it'd lead to food shortages, causing the american economy to turn to shit, leading to economic inflation, and america would be IN THE SHIT for a solid while and could easily be considered a third world country up until it realizes what to do to fix that.
air travel would also be halted, cars wouldn't be drivable, sun wouldn't be able to breach the dense as cloud, not to mention that people with respiratory issues wouldn't be able to leave the country other than by boat and they'd probably have to wear masks more often then not if they even survived it, it'd be a real shit show.
