In early August 2026, a magnitude 4.3 earthquake struck the Pisa area of Tuscany at a shallow depth. The tremor, centered near San Rossore park, was felt across several provinces, including Lucca, Livorno, and Florence. While no injuries or significant structural damage were reported, the event prompted precautionary evacuations in San Giuliano Terme and a four-hour suspension of several regional rail lines for safety inspections.

Following the initial earthquake and a magnitude 3.2 aftershock, the region has experienced a period of increased seismic activity. By August 9, the National Institute of Geophysics and Volcanology (INGV) characterized the ongoing situation as a seismic swarm consisting of frequent, low-magnitude tremors, including a magnitude 2.4 earthquake. Authorities continue to monitor the area closely.
