On October 4, 2026 at 05:55 UTC, a magnitude 4.6 shallow crustal earthquake struck 121 km WNW of Chauk, Burma (Myanmar), at a depth of 58.3 km and coordinates 21.3382°, 93.7503°. This earthquake was detected by 51 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
