2026-05-29 05:32:39 UTC (17 hours ago) · approx. 12:32 AM UTC-5 local
On May 29, 2026 at 05:32 UTC, a magnitude 5.1 shallow crustal earthquake struck 86 km S of Pacocha, Peru, at a depth of 10.0 km and coordinates -18.4158°, -71.4602°. This earthquake was detected by 71 seismic stations with good location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
