2024-07-19 02:15:52 UTC (2024-07-19) · approx. 9:15 PM UTC-5 local
On July 19, 2024 at 02:15 UTC, a magnitude 5.0 intermediate depth earthquake struck 42 km SE of San Pedro de Atacama, Chile, at a depth of 131.2 km and coordinates -23.1775°, -67.9065°. This earthquake was detected by 46 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
