On December 1, 2025 at 23:26 UTC, a magnitude 4.9 intermediate depth earthquake struck 29 km WNW of Yuyapichis, Peru, at a depth of 108.2 km and coordinates -9.5429°, -75.2302°. This earthquake was detected by 84 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.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.9 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 4.9 event is significantly smaller than that historical record.

What should I do after an earthquake?

If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
