M5.2 Earthquake near western Indian-Antarctic Ridge — October 31, 2024
2024-10-31 05:44:44 UTC (2024-10-31) · approx. 1:44 PM UTC+8 local
On October 31, 2024 at 05:44 UTC, a magnitude 5.2 shallow crustal earthquake struck near western Indian-Antarctic Ridge, at a depth of 10.0 km and coordinates -48.9029°, 121.2807°. This earthquake was detected by 55 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
