On September 10, 2026 at 06:42 UTC, a magnitude 5.3 shallow crustal earthquake struck 126 km WSW of Alianza Cristiana, Peru, at a depth of 10.0 km and coordinates -3.8730°, -77.5027°. This earthquake was detected by 66 seismic stations with good location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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.
