Ponza is an island in the Tyrrehenian Sea, in Italy. It is located west of Naples. The island is now part of the Italian Park system, but was once part of a violent undersea volcano in the Pliocene and early Pleistocene. The rocks tell the story of a storm of ash and other pyroclastic materials being spurred from fractures on the sea bottom. This volcanic eruption has stopped, and is considered extinct. However, not far from Ponza is Mount Vesuvius, which has the potential of erupting.

 


Ponza represent volcanic rocks deposited mainly underwater.
