2024-08-23 20:56:16 UTC (2024-08-23) · approx. 4:56 AM UTC+8 local
On August 23, 2024 at 20:56 UTC, a magnitude 4.3 shallow crustal earthquake struck near western Indian-Antarctic Ridge, at a depth of 10.0 km and coordinates -49.4943°, 126.6999°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
