On November 8, 2023 at 23:21 UTC, a magnitude 4.5 shallow crustal earthquake struck 197 km N of Bamboo Flat, India, at a depth of 18.4 km and coordinates 13.4736°, 92.9090°. This earthquake was detected by 30 seismic stations with good 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.
