On March 24, 2025 at 07:19 UTC, a magnitude 4.7 shallow crustal earthquake struck 196 km SE of Port Blair, India, at a depth of 10.0 km and coordinates 10.3688°, 93.9709°. This earthquake was detected by 87 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
