M5.0 Earthquake near western Indian-Antarctic Ridge — May 14, 2025
2025-05-14 05:03:52 UTC (2025-05-14) · approx. 1:03 PM UTC+8 local
On May 14, 2025 at 05:03 UTC, a magnitude 5.0 shallow crustal earthquake struck near western Indian-Antarctic Ridge, at a depth of 10.0 km and coordinates -49.5429°, 117.2451°. This earthquake was detected by 40 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
