On January 30, 2023 at 18:45 UTC, a magnitude 5.0 intermediate depth earthquake struck 105 km ENE of Port Blair, India, at a depth of 107.4 km and coordinates 12.1363°, 93.5873°. This earthquake was detected by 93 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
