On June 15, 2025 at 16:35 UTC, a magnitude 5.6 shallow crustal earthquake struck 37 km WSW of Callao, Peru, at a depth of 40.0 km and coordinates -12.1764°, -77.4434°. The earthquake was reported felt by 192 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 5.7 (strong). The USGS PAGER system issued a yellow alert level for this event, indicating local impact possible. This earthquake was detected by 102 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 754, making it a moderate-impact event. The nearest populated place is San Isidro (population 68,309).

Physical scale: An earthquake of magnitude 5.6 releases seismic energy equivalent to roughly 4 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 4.4 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 5.6 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 5.6 event is significantly smaller than that historical record.
