On August 19, 2022 at 19:06 UTC, a magnitude 4.5 intermediate depth earthquake struck near Northern Peru, at a depth of 156.5 km and coordinates -7.7897°, -74.6292°. This earthquake was detected by 38 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 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.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.5 earthquakes can continue for several days and gradually diminish over time.

Has Peru had earthquakes this big before?

The largest recorded earthquake in Peru was the M8.0 Arequipa earthquake of June 23, 2001. Today's magnitude 4.5 event is significantly smaller than that historical record.
