Can we survive if Yellowstone erupts?
Should the supervolcano lurking beneath Yellowstone National Park ever erupt, it could spell calamity for much of the USA. Deadly ash would spew for thousands of miles across the country, destroying buildings, killing crops, and affecting key infrastructure. Fortunately the chance of this occurring is very low.

A recent PBS documentary identified Kilauea, on the island of Hawaii, as “The Most Dangerous Volcano in the World.” A curious choice, in my opinion, for any rating of a volcano’s danger must take into account both the intrinsic hazard and the number of lives at risk. Eruptions of Kilauea are certainly spectacular.
