2024-06-18 22:12:11 UTC (2024-06-18) · approx. 6:12 AM UTC+8 local
On June 18, 2024 at 22:12 UTC, a magnitude 4.1 shallow crustal earthquake struck near western Indian-Antarctic Ridge, at a depth of 10.0 km and coordinates -50.1323°, 120.8959°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
