On August 7, 2026 at 00:00 UTC, a magnitude 4.5 shallow crustal earthquake struck 29 km S of Mendoza, Argentina, at a depth of 10.0 km and coordinates -33.1527°, -68.8413°. This earthquake was detected by 36 seismic stations with good location accuracy and was assigned a USGS significance rating of 313, 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.
