ITALY'S Campi Flegrei volcano has, for the first time in nearly 400 years, been “showing a type of unrest” which could indicate it is “getting ready for another eruption”, volcano expert Christopher Kilburn has said.
The volcano, which is located in the highly-populated Italian city of Naples, could at some point in the “foreseeable future” have a Vesuvian-style eruption, warned Dr Christopher Kilburn, a professor at University College London and expert in volcanic hazard. Speaking to Express.co.uk, Dr Kilburn explained how Campi Flegrei is a caldera and was produced by a large-scale eruption.
He said: “The last major collapse occurred 15,500 years ago. Since then there have been lots of small eruptions within the caldera which is populated by about 350,000 people.“The size of these eruptions is comparatively modest. When I say comparatively, the larger sizes are about the size of the Vesuvius eruption that destroyed Pompeii and Herculaneum – so fairly big for human beings but small compared with what the volcano has done in the past.”
The volcanologist, who has worked closely with the Vesuvius Observatory in Naples to analyse the volcano, explained how the last historic eruption was in 1538.
But the professor warned: “Since then it has been showing episodes of unrest – that means the ground has at the centre of the caldera the ground has been uplifted overall by just under four metres in the last 60 years or so. So, about two metres in two years with long intervals and nothing in between.”
Dr Kilburn warned the Campi Flegrei volcano is “active and will erupt again” at some point in the future.
He added: “The point is that because it is the first time in nearly 400 years that the volcano has been showing this type of unrest, there is now concern that the volcano might be getting ready for another eruption in the foreseeable future.
“But that type of eruption is of the size of possibly a Vesuvian-style or even much smaller.
“So we are not talking about another giant eruption that might produce another caldera.”
Dr Kilburn said it is “important to be aware” that the volcano is active. But he urged people living in the area not to worry, adding: “It is important to be reassured that plans are being made and not to be worried every day that something might happen because that is actually not the case.”
