A rapid increase in volcanic tremor was recorded at Mount Etna, Italy on March 24, 2025, followed by explosive activity at the Southeast Crater. The eruption occurred after tremor levels rose significantly, prompting authorities to raise the Aviation Color Code to Red at 10:18 UTC.
Floods battered parts of Italy after nearly a month’s worth of rain fell over some regions on Friday, March 14, 2025, causing rivers to swell across the country. Red alerts were in effect across Italy, including Florence and Pisa, following an extreme flooding event that triggered multiple landslides and caused widespread damage.
A shallow earthquake registered by the INGV as M4.4 hit the Campi Flegrei region of Italy at 00:25 UTC (01:25 LT) on March 13, 2025. The agency is reporting a depth of 2 km (1.2 miles). The earthquake matched the strongest event in 40 years but showed unprecedented ground accelerations, indicating greater intensity, according to the Vesuvius Observatory. The USGS and EMSC reported a magnitude of 4.2, with USGS reporting a depth of 10 km (6.2 miles) and EMSC 3 km (1.9 miles).
An increase in volcanic tremor accompanied by lava overflow from the North crater area has been observed at Stromboli volcano on February 28, 2025. The activity includes a modest lava fountain at vent N2, with the lava flow confined to the upper portion of the Sciara del Fuoco.
A new degassing pit crater was identified at 3.1 km (10 170 feet) a.s.l. on the southern flank of Etna’s Bocca Nuova Crater on February 28, 2025. A modest lava overflow was also observed from the Southeast Crater at 07:00 LT (06:00 UTC), producing a lava flow on the upper southern flank of the crater.
A new study published this month in Nature Communications reports that burst-like seismic swarms have been a defining feature of the volcanic unrest at Campi Flegrei since 2021.
Over 600 earthquakes were recorded at Campi Flegrei, Italy, between February 17 and 23, 2025, with the largest measuring M3.2. Around 1 cm (0.4 inches) of ground uplift was observed in the area of maximum deformation, coinciding with the onset of an earthquake swarm on February 15.
A drone video captured on February 24, 2025, shows the evolving lava field from an ephemeral vent at 3.05 km (10 006 feet) a.s.l. on the southwestern slope of Mount Etna, Italy.
Emergency teams rescued eight tourists who got lost on Mount Etna on Monday, February 17, 2025, amid heavy crowds and traffic congestion caused by visitors eager to witness the ongoing volcanic eruption.
An intense earthquake swarm is in progress in the Campi Flegrei volcanic caldera, southern Italy, since 15:53 UTC on February 15, 2025. More than 556 earthquakes with magnitudes up to M3.9 were registered by 13:00 UTC on February 18. As a precautionary measure, schools in the town of Pozzuoli, which is close to the epicenter of the earthquakes, are closed today.
