On December 28, 2022 at 01:49 UTC, a magnitude 4.9 shallow crustal earthquake struck 69 km NNE of Santa Rosa, Peru, at a depth of 9.0 km and coordinates -10.3543°, -74.6016°. This earthquake was detected by 78 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 370, 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.
