2025-07-08 21:32:53 UTC (2025-07-08) · approx. 4:32 PM UTC-5 local
On July 8, 2025 at 21:32 UTC, a magnitude 4.5 shallow crustal earthquake struck 22 km WSW of Changuillo, Peru, at a depth of 53.3 km and coordinates -14.7620°, -75.4116°. This earthquake was detected by 20 seismic stations with good 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 Peru, a region characterized by the northern Peru-Chile subduction zone, complicated by the subduction of the Nazca Ridge. The nearest mapped fault system is the Peru-Chile Trench. View all earthquakes in Peru.
