2024-08-06 13:15:17 UTC (2024-08-06) · approx. 8:15 AM UTC-5 local
On August 6, 2024 at 13:15 UTC, a magnitude 4.8 shallow crustal earthquake struck 96 km SW of Huanchaquito Alto, Peru, at a depth of 44.4 km and coordinates -8.6890°, -79.7344°. This earthquake was detected by 148 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.
