Overview

• INGV recorded the magnitude 4.0 event at 04:55 local time with an epicenter near Pozzuoli.
• Scientists logged at least 40 tremors within a few hours, including 23 in the early morning before the stronger quake.
• Authorities initially reported no injuries or major damage, though many residents felt the shaking across the Naples area.
• Cumana and Circumflegrea train services were suspended for safety checks, and Prefect Michele di Bari convened the civil-protection coordination center.
• The shallow focus, reported at roughly 0.3 kilometers, helped make the quake widely felt, and the episode follows stronger shocks earlier this year, including a magnitude 4.6 on June 30.
