M5.0 Earthquake 27 km NNW of Atico, Peru — July 2, 2023
2023-07-02 01:25:01 UTC (2023-07-02) · approx. 8:25 PM UTC-5 local
On July 2, 2023 at 01:25 UTC, a magnitude 5.0 shallow crustal earthquake struck 27 km NNW of Atico, Peru, at a depth of 47.8 km and coordinates -15.9842°, -73.7322°. This earthquake was detected by 127 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — 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.
