Temperatures above 40 °C (104 °F) led to the closure of over 1 350 schools in France and work restrictions across 13 Italian regions between June 30 and July 2, 2025, as a persistent heat dome caused red-level alerts and severe public health risks across southern Europe.
An earthquake swarm with the strongest quake registered as an M4.6 quake struck the Campi Flegrei area in southern Italy on June 30, 2025, prompting evacuations and train delays in the region. It was the strongest tremor to strike the region in 40 years, surpassing the M4.4 quakes of March and May.
An explosive eruption from Mount Etna’s Southeast Crater was observed at 04:33 UTC on June 19, 2025, sending ash up to 6 000 m (19 700 feet) and producing lava overflows toward Valle del Leone. As a result the Aviation Code was raised to Red.
A round of severe weather swept across parts of Italy on Monday afternoon, June 16, 2025, bringing floods, strong winds, hail, and tornadoes to multiple regions, including Modena, Bologna, Reggio Emilia, and Ravenna.
A swarm of earthquakes struck Italy’s Campi Flegrei region early Thursday, June 5, 2025, starting at 04:39 UTC. At least nine tremors were recorded within hours, the strongest reaching magnitude 3.2. The activity adds to growing concerns in an area already showing long-term signs of volcanic unrest.
Footage captured on June 2, 2025, shows people fleeing as an eruption at Mount Etna’s Southeast Crater produces pyroclastic flow and an ash plume up to 6.5 km (21 325 feet).
A sharp increase in volcanic tremor preceded a new Strombolian eruption at Mount Etna, Italy, early on June 2, 2025, with ash and SO2 clouds drifting southwest. The Aviation Color Code was raised to Red at 03:32 UTC and downgraded to Orange at 06:39 UTC.
A study of Campi Flegrei’s crust has uncovered a damaged rock layer underground that may be driving the volcano’s long-running unrest. The zone, weakened by older magma intrusions, now appears to trap gas rising from deeper sources. This buildup of underground pressure could explain both the steady ground uplift and the swarms of small quakes recorded since 2005.
A tornado struck Buja and Dignano in Italy’s Udine Province on Thursday, May 22, 2025, tearing the roof off a primary school in Dignano. The event occurred amid a broader severe weather system that brought flooding and intense rainfall to other parts of the region.
A new earthquake swarm began in the Campi Flegrei caldera at 14:23 local time on May 14, 2025, just five hours after Italy’s National Institute of Geophysics and Volcanology (INGV) reported the end of a previous swarm that led to a state of emergency declaration.
