On May 3, 2023 at 02:11 UTC, a magnitude 5.0 shallow crustal earthquake struck 35 km NW of El Cardo, Peru, at a depth of 65.8 km and coordinates -16.3605°, -72.9385°. This earthquake was detected by 71 seismic stations with good 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.
