M4.6 Earthquake in the Balleny Islands region — February 16, 2022
2022-02-16 18:49:57 UTC (2022-02-16) · approx. 6:49 AM UTC+12 local
On February 16, 2022 at 18:49 UTC, a magnitude 4.6 shallow crustal earthquake struck in the Balleny Islands region, at a depth of 10.0 km and coordinates -64.9284°, 177.4034°.
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.
