On May 24, 2025 at 11:12 UTC, a magnitude 5.0 shallow crustal earthquake struck 278 km SSE of Ushuaia, Argentina, at a depth of 10.0 km and coordinates -57.2527°, -67.3642°. This earthquake was detected by 34 seismic stations with good location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
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.
