On June 8, 2025 at 19:46 UTC, a magnitude 4.7 intermediate depth earthquake struck 26 km ESE of Londres, Argentina, at a depth of 147.5 km and coordinates -27.8354°, -66.9033°. This earthquake was detected by 64 seismic stations with excellent 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.
