On October 9, 2020 at 08:55 UTC, a magnitude 5.0 intermediate depth earthquake struck 36 km SSW of Andalgalá, Argentina, at a depth of 163.0 km and coordinates -27.8978°, -66.4050°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
