2026-05-06 11:31:43 UTC (40 min ago) · approx. 6:31 AM UTC-5 local
On May 6, 2026 at 11:31 UTC, a magnitude 4.7 shallow crustal earthquake struck 90 km WSW of Coquimbo, Chile, at a depth of 10.0 km and coordinates -30.1791°, -72.2383°. This earthquake was detected by 65 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 Chile, a region characterized by the Peru-Chile Trench, where the Nazca Plate subducts beneath South America at 65-80 mm per year. The nearest mapped fault system is the Peru-Chile Trench. View all earthquakes in Chile.
