On December 10, 2023 at 11:52 UTC, a magnitude 5.7 shallow crustal earthquake struck 53 km SSW of Paracas, Peru, at a depth of 14.0 km and coordinates -14.3228°, -76.4362°. The earthquake was reported felt by 4 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 5.3 (strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 88 seismic stations with good location accuracy and was assigned a USGS significance rating of 502, placing it among routine seismic activity. The nearest populated place is Paracas (population 1,196).

Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 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.

Where did the earthquake occur?

The earthquake epicenter was located at -14.3228°, -76.4362°, which is 53 km SSW of Paracas, Peru. The nearest populated place is Paracas (population 1,196). View all earthquakes in Peru.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.7 earthquakes can continue for days to weeks 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 5.7 event is significantly smaller than that historical record.
