2026-08-26 22:23:12 UTC (1 day ago) · approx. 5:23 PM UTC-5 local
On August 26, 2026 at 22:23 UTC, a magnitude 4.7 intermediate depth earthquake struck 22 km ENE of Talca, Chile, at a depth of 80.6 km and coordinates -35.3195°, -71.4471°. This earthquake was detected by 32 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.
