2026-07-28 13:24:33 UTC (1 hour ago) · approx. 8:24 AM UTC-5 local
On July 28, 2026 at 13:24 UTC, a magnitude 5.2 shallow crustal earthquake struck 151 km WSW of Puerto Santa, Peru, at a depth of 9.7 km and coordinates -9.6737°, -79.8368°. This earthquake was detected by 128 seismic stations with good location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 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.
