On August 2, 2023 at 00:10 UTC, a magnitude 5.3 shallow crustal earthquake struck 287 km SSE of Port Blair, India, at a depth of 10.0 km and coordinates 9.3458°, 93.9282°. This earthquake was detected by 159 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
