M4.6 Earthquake 11 km ESE of Corani, Peru — January 23, 2022
2022-01-23 21:33:52 UTC (2022-01-23) · approx. 4:33 PM UTC-5 local
On January 23, 2022 at 21:33 UTC, a magnitude 4.6 shallow crustal earthquake struck 11 km ESE of Corani, Peru, at a depth of 10.0 km and coordinates -13.9084°, -70.5047°.
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.
