On August 19, 2023 at 15:20 UTC, a magnitude 4.8 shallow crustal earthquake struck 31 km S of Tezpur, India, at a depth of 35.0 km and coordinates 26.3499°, 92.8450°. This earthquake was detected by 47 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 360, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
