Seismic Activity and Earthquake Swarms

Seismic activity in the Campi Flegrei area includes frequent earthquake swarms, which are a series of earthquakes striking in a relatively short amount of time.

These swarms are often concentrated around the Solfatara Crater or under the Gulf of Pozzuoli.

The magnitude of these quakes is usually low to moderate, with the epicenter often shallow, indicating magma movement beneath the crust.

Ground Deformation and Uplift Phenomena

Ground deformation is a telltale sign of volcanic activity within Campi Flegrei, characterized by the periodic ground uplift, also known as bradyseism.

This phenomenon refers to the slow vertical movement of the Earth’s surface and can be observed in areas such as the Solfatara Crater and the wider caldera.

Ground deformation data underscore the dynamic nature of the underlying magma chamber and the stress it places on the overlying crust.

Measuring and Monitoring Volcanic Health

To keep tabs on the caldera’s health, an array of geophysical instruments is deployed throughout the region.

These devices measure seismicity, thermal energy release from fumaroles, and various other geological changes.

Scientists pay close attention to the trends in this data, particularly around the Solfatara Crater, to predict any significant changes in volcanic activity.
