2024-09-14 10:56:45 UTC (2024-09-14) · approx. 4:56 PM UTC+6 local
On September 14, 2024 at 10:56 UTC, a magnitude 4.9 shallow crustal earthquake struck in the Nicobar Islands, India region, at a depth of 10.0 km and coordinates 6.1850°, 92.1763°. This earthquake was detected by 67 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.
