2022-07-16 11:39:15 UTC (2022-07-16) · approx. 9:39 AM UTC-2 local
On July 16, 2022 at 11:39 UTC, a magnitude 4.9 shallow crustal earthquake struck near Scotia Sea, at a depth of 10.0 km and coordinates -60.3210°, -33.1070°. This earthquake was detected by 36 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.
