M4.8 Earthquake 68 km E of Arica, Chile — November 30, 2024
2024-11-30 18:34:56 UTC (2024-11-30) · approx. 1:34 PM UTC-5 local
On November 30, 2024 at 18:34 UTC, a magnitude 4.8 intermediate depth earthquake struck 68 km E of Arica, Chile, at a depth of 118.3 km and coordinates -18.3641°, -69.6619°. This earthquake was detected by 87 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.
