2023-11-09 17:50:27 UTC (2023-11-09) · approx. 12:50 PM UTC-5 local
On November 9, 2023 at 17:50 UTC, a magnitude 5.1 intermediate depth earthquake struck 11 km W of San Pablo, Peru, at a depth of 127.6 km and coordinates -6.7886°, -76.6766°. This earthquake was detected by 72 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
