Generally, one would want to be more than 1000km from the eruption site. Ash would cover crops and so on, but you're not going to be obliterated. Yes, the crop failures and cascading effects would render much of the world food source inoperable for some time, but also would replenish the midwest topsoil.
How long ash would remain airborne would also have an impact on crops elsewhere and could result in mini ice-age conditions.
Still not the end of the current civilization.
Also, Yellowstone is not the only supervolcano around.
- stjohnswarts 4y agoI thought if yellowstone had a mega eruption that all civilization in North America would be toast and it would cause havoc with weather over the entire planet?
- mc32 4y agoI guess it depend on what you mean. Will it kill all people in NA? No. Will it severely and catastrophically affect the US and Canada? Yes. But the people who remain should be able to recover if we have enough food to take us though some years of lost crops and bad crops. Would adversaries take advantage? Most likely but we do have allies and most adversaries would also be affected by the following mini ice-age conditions if ash remains airborne for years.
