2025-02-18 17:00:49 UTC (2025-02-18) · approx. 12:00 PM UTC-5 local
On February 18, 2025 at 17:00 UTC, a magnitude 5.0 intermediate depth earthquake struck 9 km NW of Mariposa, Peru, at a depth of 103.4 km and coordinates -11.3467°, -74.8175°. This earthquake was detected by 91 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
