2026-08-27 11:47:16 UTC (2 hours ago) · approx. 4:47 PM UTC+5 local
On August 27, 2026 at 11:47 UTC, a magnitude 4.9 shallow crustal earthquake struck near Indian Ocean Triple Junction, at a depth of 10.0 km and coordinates -26.0744°, 70.7736°. This earthquake was detected by 31 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
