M5.0 Earthquake near Southwest Indian Ridge — December 15, 2025
2025-12-15 19:48:31 UTC (2025-12-15) · approx. 11:48 PM UTC+4 local
On December 15, 2025 at 19:48 UTC, a magnitude 5.0 shallow crustal earthquake struck near Southwest Indian Ridge, at a depth of 10.0 km and coordinates -28.3037°, 62.7506°. This earthquake was detected by 63 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.
