2026-10-30 22:46:57 UTC (1 hour ago) · approx. 5:46 PM UTC-5 local
On October 30, 2026 at 22:46 UTC, a magnitude 4.6 intermediate depth earthquake struck 33 km NE of Mazo Cruz, Peru, at a depth of 194.8 km and coordinates -16.5439°, -69.4844°. This earthquake was detected by 55 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 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.
