On May 17, 2026 at 09:38 UTC, a magnitude 4.6 shallow crustal earthquake struck 266 km ESE of Port Blair, India, at a depth of 10.0 km and coordinates 11.0493°, 95.1108°. This earthquake was detected by 42 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
