Felt by 85 people across nearby locations.
On November 28, 2021 at 06:32 UTC, a magnitude 5.1 shallow crustal earthquake struck 34 km W of Callao, Peru, at a depth of 61.6 km and coordinates -12.0155°, -77.4324°.
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.
