A long-quiet yet huge supervolcano that lies under 500,000 people in Italy may be waking up and approaching a “critical state,” scientists report this week in the journal Nature Communications.
Based on physical measurements and computer modeling, “we propose that magma could be approaching the CDP [critical degassing pressure] at Campi Flegrei, a volcano in the metropolitan area of Naples, one of the most densely inhabited areas in the world, and where accelerating deformation and heating are currently being observed,” wrote the scientists—who are led by Giovanni Chiodini of the Italian National Institute of Geophysics in Rome.
All long known about of course. Just one thing:
A smaller but still sizable eruption was observed at the supervolcano in 1538. That event lasted eight days and created the mountain Monte Nuovo. But since then, the volcano has been quiet, slumbering for more than 500 years.
I spent a couple of years of my childhood living on Monte Nuovo.
