Regione Campania

The Campania is a region of southern Italy, on the western coast of the "boot". It is south of Rome, with the Capital Napoli (Naples) right in the center.

This region is the center of Italian volcanism, with the volcano Vesuvio right behind the Capital. The whole area is covered by volcanic rocks and volcanic ashes. The last explosive eruption 79 AD produced several tens of meters of ash covering Pompei and Harculaneum. This rocks are not soluble and thus not karstified. Lava tubes also do not exist, as the volcanism is explosive. Lava tubes are formed by calm lava which flows over a long time.

But because of the long history, especially the Roman empire, there are numerous subterranea, which were cut into the soft volcanic tufa.

At the southern part of this area are several limestone areas with impressive caves. Especially the sea caves with their strange filtered light, like Grotta Azzurra and Grotta Smeralda, are world famous.
