2024-10-19 22:26:15 UTC (2024-10-19) · approx. 5:26 PM UTC-5 local
On October 19, 2024 at 22:26 UTC, a magnitude 4.6 intermediate depth earthquake struck 119 km E of Diego de Almagro, Chile, at a depth of 106.6 km and coordinates -26.3158°, -68.8537°. This earthquake was detected by 106 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — 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.
