The world survived many VEL’s of 10 or more, but humanity barely survived one ... and that was 2800 times greater than the Mt St Helens eruption. This one could be bigger still as it historically has been ...
Lots of good farmland will do you went there is no sun for years, and the temperature drops an average of 38 degrees ...
The little eruptions of Yellowstone are not what the watchers are worried about ... it is over due, not for a little eruption, but a big one ...
No one knows what will occur next, small or large. Further, the super volcano has erupted before and we are here and so are many species.
Will the sun be blocked for years so that no crops can grow?
Doubtful but even then there is nothing to stop power generation, greenhouses with artificial sunlight, etc over most of the planet.
Anything can happen I’m not convinced humanity let’s say in the East or in South America would be wiped out even by a super volcano here.
