Q

Potential effects of an eruption

A

National: two thirds of the USA would be uninhabitable, water supply contaminated
Global: Global temperatures lowers by 20°C because the ash cloud would obscure the sun. Change in climate would take 6-10 years to return to normal. Food chain very disrupted, people and animals die, monsoon would fail- mass starvation.
