M4.7 Earthquake 20 km E of Torata, Peru — June 21, 2026
2026-06-21 08:50:14 UTC (2026-06-21) · approx. 3:50 AM UTC-5 local
On June 21, 2026 at 08:50 UTC, a magnitude 4.7 intermediate depth earthquake struck 20 km E of Torata, Peru, at a depth of 123.6 km and coordinates -17.0910°, -70.6468°. This earthquake was detected by 53 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
