A slumbering Campi Flegrei volcano under the Italian city of Naples shows signs of “reawakening” and may be nearing a critical pressure point, according to a study published on Tuesday.Italian and French scientists have for the first time identified a threshold beyond which rising magma under the Earth’s surface could trigger the release of fluids and gases at a ten-fold increased rate.This would cause the injection of high-temperature steam into surrounding rocks, said lead author Giovanni Chiodini, a researcher at Italy’s National Institute of Geophysics and Volcanology in Bologna.
