Scientists are closely monitoring Campi Flegrei, a supervolcano in Italy, which has shown signs of increased activity, including hundreds of small earthquakes and gas emissions. The region, mostly quiet since 1538, has a yellow alert level due to ongoing seismic events and concerns over magma movement beneath the surface. Experts warn that an eruption could have severe consequences, potentially affecting global climate, but emphasize that while preparation is essential, the likelihood of a major eruption occurring soon remains uncertain.
