Phlegraean Fields, Italy
The Phlegraean Fields, is a large volcanic area situated to the west of Naples, Italy. It was declared a regional park in 2003. The area of the caldera consists of 24 craters and volcanic edifices; most of them lie under water. Hydrothermal activity can be observed at Lucrino, Agnano and the town of Pozzuoli. There are also effusive gaseous manifestations in the Solfatara crater, the mythological home of the Roman god of fire, Vulcan. This area is monitored by the Vesuvius Observatory. The area also features bradyseismic phenomena, which are most evident at the Macellum of Pozzuoli (misidentified as a temple of Serapis): bands of boreholes left by marine molluscs on marble columns, show that the level of the site in relation to sea level has varied.

The Phlegraean Fields hide one of the most violent volcanoes on the entire planet, covering an area of about 100 square kilometres. The Fields are located in the Gulf of Pozzuoli west of Naples.
A study reported by Le Scienze shows the Phlegraean Fields could be on the verge of an eruption: currently the area is on a 'yellow alert' because of recent ground movements.
These image comparisons were created using Copernicus Sentinel-2 imagery, and aim to show the ground changes in the Phlegraean Fields using both true and false colour processing.
