On November 26, 2023 at 19:24 UTC, a magnitude 4.5 shallow crustal earthquake struck 296 km ENE of Port Blair, India, at a depth of 10.0 km and coordinates 12.6576°, 95.2787°. This earthquake was detected by 34 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
