Campi Flegrei : Recent Phenomenon
The strongest earthquake to hit Italy’s Campi Flegrei supervolcano region in decades struck recently.
- Campi Flegrei is an active volcanic area located in the vicinity of Naples, Italy.
- Unlike the nearby Mount Vesuvius, Campi Flegrei is not characterised by a single volcano.
- It is more of a volcanic system, with several centres situated within a caldera (the depression created when emptying magma chambers causes the roof of a volcano to collapse).
- The Campi Flegrei caldera has a diameter of about 12-15 km (7.5-9.3 miles).
- It was formed 39,000 years ago after an eruption emptied it of magma. According to a new hypothesis, this eruption could have been the beginning of the end of the Neanderthal.
- One-third of it lies under the Tyrrhenian Sea, between the Italian mainland and the country’s island of Sardinia.
- It is the largest active caldera in Europe.
- It is much larger than the cone-shaped Vesuvius, which destroyed the ancient Roman city of Pompeii in AD79 and is much more active.
- Campi Flegrei has been in a restless state since 1950.
- It is a result of a phenomenon known as bradyseism, which scientists understand to be the gradual movement of part of Earth’s surface caused by the filling or emptying of an underground magma chamber or hydrothermal activity.
