Two ‘supervolcanoes’ are showing signs of waking up

Two “supervolcanoes,” the Campi Flegrei in Italy and the Long Valley Caldera in California, have shown signs of waking up. The Campi Flegrei region has experienced over a thousand small earthquakes, indicating a potential eruption. However, experts believe that neither volcano is currently at risk of a major eruption. Supervolcanoes are difficult to predict and are characterized by massive explosions. The Long Valley Caldera has shown signs of cooling magma.
