M4.6 Earthquake in the Balleny Islands region — July 16, 2020
2020-07-16 01:29:49 UTC (2020-07-16) · approx. 1:29 PM UTC+12 local
On July 16, 2020 at 01:29 UTC, a magnitude 4.6 shallow crustal earthquake struck in the Balleny Islands region, at a depth of 10.0 km and coordinates -65.3261°, 178.8103°.
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.
