2025-02-26 18:11:21 UTC (2025-02-26) · approx. 7:11 PM UTC+1 local
On February 26, 2025 at 18:11 UTC, a magnitude 4.5 intermediate depth earthquake struck 39 km W of San Nicolò, Italy, at a depth of 188.4 km and coordinates 38.6421°, 15.3939°. This earthquake was detected by 111 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Italy, a region characterized by the Apennine extensional belt and Calabrian subduction zone, where Africa-Eurasia convergence produces complex faulting. View all earthquakes in Italy.
