2024-05-16 02:39:11 UTC (2024-05-16) · approx. 9:39 PM UTC-5 local
On May 16, 2024 at 02:39 UTC, a magnitude 4.8 shallow crustal earthquake struck 66 km SW of Santiago, Peru, at a depth of 25.0 km and coordinates -14.5260°, -76.2206°. This earthquake was detected by 27 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
