Hundreds of small tremors have shaken a densely populated volcanic area west of the Italian city of Naples in recent weeks, pushing the government to quickly redraft mass evacuation plans, even though experts don’t see an imminent risk of eruption.
In the latest of a long string of tremors, a 4.0-magnitude earthquake hit the region of Campi Flegrei (Phlegraean Fields) Monday. The region is home to a caldera, a cauldron-shaped depression left behind by the eruption of a very large volcano.
