Overview

  • A magnitude-4.0 quake struck beneath the Campi Flegrei caldera at 9:15 a.m. local time on July 18, driving Neapolitans into the streets.
  • INGV data and Italian media report no injuries or significant damage from the latest tremor.
  • The Vesuvian Observatory recorded an ongoing seismic swarm, building on quakes that have shaken the supervolcano since May 2024 and included a record 4.6-magnitude shock on June 30.
  • Campi Flegrei has remained at yellow alert since 2014, with geophysicists tracking ground uplift and seismic trends to guide response.
  • Authorities in Rome have prepared evacuation strategies for hundreds of thousands, but limited turnout in recent drills highlights community engagement challenges.
