On March 11, 2025 at 14:08 UTC, a magnitude 5.6 deep-focus earthquake struck 126 km WNW of Iñapari, Peru, at a depth of 648.3 km and coordinates -10.4790°, -70.6352°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 226 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 482, placing it among routine seismic activity. The nearest populated place is San Lorenzo (population 0).

Physical scale: An earthquake of magnitude 5.6 releases seismic energy equivalent to roughly 4 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 4.4 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.
