2026-05-12 05:18:57 UTC (1 hour ago) · approx. 11:18 AM UTC+6 local
On May 12, 2026 at 05:18 UTC, a magnitude 4.9 shallow crustal earthquake struck in the Nicobar Islands, India region, at a depth of 10.0 km and coordinates 7.0489°, 92.4295°. This earthquake was detected by 56 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.
