On May 23, 2025 at 20:10 UTC, a magnitude 4.0 shallow crustal earthquake struck 58 km E of Caucete, Argentina, at a depth of 10.0 km and coordinates -31.6158°, -67.6694°.

Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
