M5.0 Earthquake near South Shetland Islands — October 10, 2020
2020-10-10 20:58:37 UTC (2020-10-10) · approx. 4:58 PM UTC-4 local
On October 10, 2020 at 20:58 UTC, a magnitude 5.0 shallow crustal earthquake struck near South Shetland Islands, at a depth of 10.0 km and coordinates -62.3293°, -58.1804°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
