Global Volcanic Activity: A Comprehensive Look at Recent Events
Campi Flegrei: Italy’s Restless Volcano
The Campi Flegrei volcano near Naples, Italy, has been showing increased activity, raising concerns among residents and scientists alike. On March 13, 2025, a magnitude 4.4 earthquake struck the area, followed by a magnitude 3.9 quake just an hour ago. These tremors, occurring at a shallow depth of 2.5 km, have caused significant ground acceleration and shaking, with some areas experiencing up to 0.6-1 g-force.
The epicenter was located near the coast, halfway between Pozzuoli and Bagnoli. The quake was widely felt in Naples and even beyond, prompting fears of a potential volcanic eruption. The national volcano observatory INGV in Naples has shared updates, reassuring the public that while there are variations in ground deformation and CO2 emissions, there is no imminent threat of an eruption.
Historical Context and Recent Events
The recent earthquakes are part of an ongoing crisis that has seen increased seismic activity over the past decade. Notable quakes prior to the March 13 event include:
- September 27, 2023: Magnitude 4.2
- October 2, 2023: Magnitude 4.0
- May 20, 2024: Magnitude 4.4
- July 26, 2024: Magnitude 4.0
Despite the increase in activity, the majority of recorded events have been of magnitude ≤ 1.0, accounting for about 97% of all events.

FAQ Section
Q: What causes volcanic activity to increase?
A: Increased volcanic activity can be due to a variety of factors, including magma movement, tectonic plate shifts, and changes in gas emissions.
Q: How do scientists monitor volcanic activity?
A: Scientists use a combination of seismometers, gas analyzers, and satellite imagery to monitor volcanic activity and predict potential eruptions.
Q: What should residents near active volcanoes do?
A: Residents should stay informed through local authorities and be prepared to evacuate if necessary. Following safety guidelines and having an emergency plan in place is crucial.
