4.7 Quake Strikes Campi Flegrei Supervolcano Near Naples

Experts warn the shock and its continuing aftershocks reflect rising bradyseismic unrest that keeps the densely populated Naples region on heightened alert.

Overview

  • The quake measured magnitude 4.7 and struck under the Campi Flegrei caldera on Friday evening, producing dozens of aftershocks reported by Italy’s INGV.
  • Local authorities reported structural damage and rockfalls concentrated in Pozzuoli, with streets and parked cars hit by falling tuff blocks and collapsed facades.
  • Official injury totals vary by outlet, with authorities citing about 21 people hurt and other reports raising the count into the mid‑20s; two to several patients were treated seriously.
  • Transport and utilities were disrupted after the shock when a high‑voltage mast fell and rail and ferry services in the Naples hub were suspended for safety checks.
  • Emergency shelters, municipal crisis centers and building inspections are active while scientists say an eruption is not predicted but that rising bradyseismic activity requires preparedness and close monitoring.
