2024-01-11 22:34:24 UTC (2024-01-11) · approx. 5:34 PM UTC-5 local
On January 11, 2024 at 22:34 UTC, a magnitude 4.5 intermediate depth earthquake struck 56 km ENE of Los Andes, Chile, at a depth of 112.3 km and coordinates -32.6204°, -70.0493°. This earthquake was detected by 33 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — 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.
