2025-12-11 11:01:12 UTC (2025-12-11) · approx. 9:01 AM UTC-2 local
On December 11, 2025 at 11:01 UTC, a magnitude 4.9 shallow crustal earthquake struck near Scotia Sea, at a depth of 10.0 km and coordinates -61.2388°, -36.4468°. This earthquake was detected by 39 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
