2020-10-14 20:16:09 UTC (2020-10-14) · approx. 3:16 PM UTC-5 local
On October 14, 2020 at 20:16 UTC, a magnitude 4.3 intermediate depth earthquake struck 51 km ESE of Los Andes, Chile, at a depth of 116.9 km and coordinates -33.0231°, -70.0999°.
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.
