Question

What will happen to asia and nevada yellowstone and or lake toba erupts?

Answer 1

If Toba or Yellowstone erupts again there will be world wide climactic changes just like the last time.  Toba , about 75 thousand years ago caused a population bottleneck in the human race which only a few thousand individuals survived.  Because of this all humans are far more closely related than would normally be the case.  People living next to the supervolcanoes will die sooner, but eventually a majority of the population will die.
