2025-07-14 19:37:04 UTC (2025-07-14) · approx. 2:37 PM UTC-5 local
On July 14, 2025 at 19:37 UTC, a magnitude 4.6 intermediate depth earthquake struck 17 km NNE of Calana, Peru, at a depth of 112.3 km and coordinates -17.7979°, -70.1269°. This earthquake was detected by 61 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.
