M4.6 Earthquake near Scotia Sea — August 30, 2026
2026-08-30 05:40:14 UTC (2026-08-30) · approx. 2:40 AM UTC-3 local
On August 30, 2026 at 05:40 UTC, a magnitude 4.6 shallow crustal earthquake struck near Scotia Sea, at a depth of 10.0 km and coordinates -60.2509°, -47.2260°. This earthquake was detected by 23 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
