Scientists at Aberdeen University have studied the sea to discover the route taken by hot fluids which feed a supervolcano in southern Italy.
Researchers used the seismic noise of waves crashing against the coastline near Campi Flegrei, which last erupted 500 years ago, to map the volcano’s inner structure.
The study was led by Professor Luca De Siena, Dr Carmelo Sammarco and Dr David Cornwell from the School of Geosciences, alongside the Vesuvius Observatory – an advisory body.
Prof De Siena said: “By using the noise at the seashore to create a seismic image, we finally have a better idea of how volcanic material travels from the depths of the volcano to the surface.
“This is important as it improves our understanding of the character of the volcano, which may ultimately improve monitoring and early warning procedures in an area inhabited by millions of people.”
