M4.8 Earthquake 71 km ENE of San Ignacio, Peru — June 25, 2022
2022-06-25 16:11:25 UTC (2022-06-25) · approx. 11:11 AM UTC-5 local
On June 25, 2022 at 16:11 UTC, a magnitude 4.8 shallow crustal earthquake struck 71 km ENE of San Ignacio, Peru, at a depth of 10.0 km and coordinates -4.8560°, -78.4254°. This earthquake was detected by 89 seismic stations with excellent 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.
