On June 28, 2026 at 15:51 UTC, a magnitude 4.2 intermediate depth earthquake struck 101 km ENE of Port Blair, India, at a depth of 99.9 km and coordinates 12.1405°, 93.5465°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
