Deep underground in southern Italy, just outside the city of Naples, the Campi Flegrei supervolcano has been resting for the past 500 years. But it seems the quiet phase may soon come to an end.

It had a significant period of unrest that culminated in the early 80s without producing an eruption. The relatively small eruption in the 1500s lasted a week or so and built a small cinder cone. The effects of that eruption were very localized. A small eruption is much more likely than a repeat of the huge 35,000+ y/o eruption that produced the Neapolitan Yellow Tuff. That small eruption could happen in 2013, or it could happen in 3013 or anytime. Suggesting an eruption is right around the corner is wildly conjectural. The media loves to over-emphasize the risk of a "super-eruption" in spite of the fact that such events are very rare and extremely unlikely to happen in any particular lifetime.
