Seismic Activity in Campi Flegrei: February 2025 Earthquake Swarm
An earthquake swarm in Campi Flegrei, Italy, produced 63 earthquakes with a maximum magnitude of 3.1 on February 5, 2025. This region has experienced 449 localized earthquakes this year, indicating increasing seismic activity, with scientists investigating the potential connections to magmatic processes or tectonic shifts.
On February 5, 2025, an earthquake swarm commenced in the Campi Flegrei volcanic region of southern Italy, beginning at 08:03 local time. A total of 63 earthquakes were recorded between 08:03 and 13:05 LT, with the strongest magnitude measuring 3.1 at a depth of 0.3 kilometers. The Italian National Institute of Geophysics and Volcanology (INGV) indicated that these seismic events vary significantly in depth, from 0.1 to 4.4 kilometers. In total, the year 2025 has seen 449 localized earthquakes in this region, highlighting a pattern of increasing activity.
Campi Flegrei is a highly significant and closely monitored volcanic area west of Naples, Italy. It is known for its complex geological features including ground deformation, fumarolic activity, and high seismicity stemming from underlying magmatic and hydrothermal systems. Historically, Campi Flegrei has undergone cycles of uplift and subsidence, with its geological activity dating back approximately 47,000 years, including two major explosive eruptions responsible for the formation of the caldera.
The ongoing earthquake swarm in Campi Flegrei underlines the area’s geological volatility and serves as a reminder of the potential risks posed by active volcanic systems. Researchers are examining whether this sequence of events is connected to subsurface magmatic processes or tectonic movements within the caldera. Continuous monitoring is essential given Campi Flegrei’s history of eruptions and significant geothermal activity.
