M4.7 Earthquake 77 km WSW of Paramonga, Peru — February 2, 2022
2022-02-02 22:16:28 UTC (2022-02-02) · approx. 5:16 PM UTC-5 local
On February 2, 2022 at 22:16 UTC, a magnitude 4.7 shallow crustal earthquake struck 77 km WSW of Paramonga, Peru, at a depth of 49.6 km and coordinates -10.9468°, -78.4868°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
