On October 10, 2022 at 19:34 UTC, a magnitude 4.5 intermediate depth earthquake struck 111 km NW of San Jos? de J?chal, Argentina, at a depth of 114.5 km and coordinates -29.4123°, -69.4101°. 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.
