2024-10-24 17:39:27 UTC (2024-10-24) · approx. 1:39 PM UTC-4 local
On October 24, 2024 at 17:39 UTC, a magnitude 4.8 intermediate depth earthquake struck 115 km ESE of Ollagüe, Chile, at a depth of 184.7 km and coordinates -21.7259°, -67.2722°. This earthquake was detected by 43 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
