2021-11-24 22:03:08 UTC (2021-11-24) · approx. 5:03 PM UTC-5 local
On November 24, 2021 at 22:03 UTC, a magnitude 4.3 shallow crustal earthquake struck 62 km WNW of Talcahuano, Chile, at a depth of 11.9 km and coordinates -36.4867°, -73.7550°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
