2026-03-12 04:41:06 UTC (2026-03-12) · approx. 11:41 PM UTC-5 local
On March 12, 2026 at 04:41 UTC, a magnitude 4.9 intermediate depth earthquake struck 21 km S of Yauri, Peru, at a depth of 136.6 km and coordinates -14.9802°, -71.3761°. This earthquake was detected by 78 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
