Overview
- The Istituto Nazionale di Geofisica e Vulcanologia recorded a magnitude 4.5 in the southern Tyrrhenian Sea on Friday, July 24, with an epicenter near Stromboli and a hypocenter around 245 km.
- Shortly after midnight on Saturday, July 25, INGV logged a magnitude 4.1 centered near Pizzone in the province of Isernia at roughly 10 km depth that was felt across Molise, Abruzzo and parts of Campania.
- Local residents reported leaving homes and some spending the night outdoors or in cars, and regional authorities conducted inspections while reporting no confirmed injuries or major structural damage.
- A smaller magnitude 2.2 aftershock was recorded in the same Molise area at about 03:41 at a depth near 9 km, and civil protection teams are maintaining active monitoring of the sequence.
- Seismologists note the pair fits recent lower Tyrrhenian activity and highlights how depth strongly affects surface shaking, a factor officials will watch as they assess aftershocks and local resilience.
