Italy's Restless Supervolcano Nears Breaking Point, Experts Warn.

Campi Flegrei, an Italian volcano that last erupted in 1538, is becoming more restless and could erupt again, according to a new study. Geologists used modeling of recent earthquake activity and ground uplift to show the volcano is "stretched nearly to a breaking point" and could rupture. The scientists say this modeling is the first of its kind in an attempt to forecast the rupture of an active volcano. The team plans to apply this model to other volcanoes.
