On May 30, 2022 at 20:41 UTC, a magnitude 4.5 intermediate depth earthquake struck 78 km S of Chamical, Argentina, at a depth of 135.4 km and coordinates -31.0699°, -66.3291°. This earthquake was detected by 52 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
