Felt by 31 people across nearby locations.
On June 17, 2020 at 00:50 UTC, a magnitude 4.8 shallow crustal earthquake struck 10 km NNW of Talcahuano, Chile, at a depth of 24.2 km and coordinates -36.6370°, -73.1553°.
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.
