On October 14, 2026 at 03:11 UTC, a magnitude 4.9 shallow crustal earthquake struck 16 km WSW of La Tirana, Chile, at a depth of 44.9 km and coordinates -20.3552°, -70.2699°. This earthquake was detected by 67 seismic stations with good location accuracy and was assigned a USGS significance rating of 372, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
