Mount Etna in Sicily is currently erupting. Most don’t recognize that it is part of the dangerous Campanian Volcanic Arc that extends along Italy and wraps around southern Sicily. A Campanian eruption 39,000 years ago was probably the second most powerful eruption in the world in the last million years, and it may have finished off the already declining Neanderthal population. We’re all familiar with the plaster cast people of Pompeii – those are from another eruption of this arc that occurred south of Naples in 79 AD. It’s estimated that 1.5 to 2 million people are at risk from a “supervolcano timebomb” that could explode at any time (see attached article).
