On May 11, 2023 at 20:44 UTC, a magnitude 4.5 shallow crustal earthquake struck 94 km S of Saiha, India, at a depth of 51.1 km and coordinates 21.6539°, 93.1376°. This earthquake was detected by 69 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
