On March 14, 2026 at 17:36 UTC, a magnitude 4.7 shallow crustal earthquake struck 51 km SSW of Lago Puelo, Argentina, at a depth of 9.1 km and coordinates -42.4502°, -71.9467°. This earthquake was detected by 58 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
