2023-09-27 23:46:44 UTC (2023-09-27) · approx. 5:46 AM UTC+6 local
On September 27, 2023 at 23:46 UTC, a magnitude 4.0 shallow crustal earthquake struck 135 km NNE of Shi Yomi, India, at a depth of 10.0 km and coordinates 29.7208°, 94.6666°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
