Felt by 1 person across nearby locations.
On September 12, 2026 at 08:46 UTC, a magnitude 4.5 shallow crustal earthquake struck 63 km WSW of Santiago, Peru, at a depth of 24.1 km and coordinates -14.4855°, -76.2161°. This earthquake was detected by 42 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.
