Italy remains exciting. Sometimes Mount Etna spits high fire fountains into the air in Sicily. Sometimes Mount Vesuvius at Naples makes a name for itself, because the pressure is growing under the volcano. In Italy, there are several active volcanic zones, the cause of which is the continental plates of Africa and Europe to be glided on each other. Mount Vesuvius, probably the most dangerous and unpredictable volcano, is located in the immediate vicinity of the densely populated province of Naples. The biggest activities take place among the phlegrean fields (Campi Flegrei), which range from Pozzuoli under the sea to the island of Ischia.
