Felt by 11 people across nearby locations.
On May 20, 2024 at 19:46 UTC, a magnitude 4.2 shallow crustal earthquake struck 3 km ENE of Procida, Italy, at a depth of 8.8 km and coordinates 40.7649°, 14.0510°. This earthquake was detected by 33 seismic stations with good location accuracy and was assigned a USGS significance rating of 276, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 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.
