Current Situation at the Phlegraean Fields
The Phlegraean Fields, a supervolcanic caldera located close to Naples and home to approximately 500,000 residents, has seen rising seismic activity in recent decades. The last volcanic eruption here occurred in 1538. On July 31, a powerful earthquake struck the area—one of the strongest in decades—prompting nearly 5,700 residents of Pozzuoli to evacuate their homes. In response, the Italian government has rolled out a decade-long recovery plan worth €1 billion, which includes subsidies covering up to 70% of the costs for reinforcing private residences against earthquakes.
Historical Background and Reinforcement Efforts
During the 1970s and 1980s, minor underground tremors led to the evacuation of tens of thousands from Pozzuoli’s historic center. Local authorities invested close to €200 million to transform the abandoned area into a tourist destination. However, recent earthquakes have caused significant damage to buildings, including 20 historic Catholic churches dating back to the 17th century. To address this, the government has allocated €10 million specifically for seismic strengthening of Pozzuoli’s churches.
Since 1950, the ground level around Pozzuoli has risen by roughly 4.6 meters due to geological shifts within the caldera, such as rock fracturing and fault movements. The Vesuvius Observatory continuously monitors seismic activity, gas emissions, and ground deformation around the clock to provide early warnings.

Yet, volcanologist Christopher Kilburn cautions that “there is no clear evidence indicating an eruption is imminent,” highlighting the complexity and uncertainty facing scientists and authorities.
The earthquake aftermath has left many Pozzuoli residents struggling with housing and economic difficulties. For example, local resident Anna Nasti receives €750 monthly to cover rent following the quake. Italy’s Civil Protection Minister, Nello Musumeci, emphasizes that while the government cannot eliminate all risks, it is committed to reducing danger and vulnerability. He also stresses promoting voluntary relocation from the most at-risk buildings and areas.
Residents of the Phlegraean Fields are working to adapt to these challenging circumstances. Roberto Della Rocca notes a strong desire among locals “to return to normal life,” though he acknowledges the ongoing tension between emergency conditions and everyday routines in Pozzuoli.
This situation underscores the vulnerability of communities facing natural disasters, especially in geologically active zones. Italy’s substantial investment in infrastructure reinforcement and risk mitigation reflects a strategic effort to safeguard lives and properties. Continuous monitoring and scientific research remain vital to ensuring public safety in this hazardous region.
