Felt by 16 people across nearby locations.
On April 27, 2023 at 06:07 UTC, a magnitude 5.0 intermediate depth earthquake struck near Maule, Chile, at a depth of 85.9 km and coordinates -35.6137°, -71.3001°. This earthquake was detected by 111 seismic stations with good location accuracy and was assigned a USGS significance rating of 391, 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.
