2025-10-24 22:59:02 UTC (2025-10-24) · approx. 6:59 AM UTC+8 local
On October 24, 2025 at 22:59 UTC, a magnitude 4.4 shallow crustal earthquake struck near western Indian-Antarctic Ridge, at a depth of 10.0 km and coordinates -47.8048°, 116.0397°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
