2023-05-24 18:28:55 UTC (2023-05-24) · approx. 1:28 PM UTC-5 local
On May 24, 2023 at 18:28 UTC, a magnitude 4.4 shallow crustal earthquake struck 169 km WSW of Lebu, Chile, at a depth of 9.8 km and coordinates -38.3835°, -75.3185°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
