On May 14, 2023 at 21:43 UTC, a magnitude 4.0 shallow crustal earthquake struck 227 km SSE of Port Blair, India, at a depth of 9.8 km and coordinates 9.7587°, 93.5283°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
