On April 28, 2024 at 19:31 UTC, a magnitude 4.8 intermediate depth earthquake struck 89 km NW of Ollagüe, Chile, at a depth of 114.0 km and coordinates -20.5963°, -68.7891°. This earthquake was detected by 50 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 355, 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.
