On April 11, 2026 at 21:21 UTC, a magnitude 4.5 shallow crustal earthquake struck 16 km W of Zibihu, China, at a depth of 10.0 km and coordinates 26.1409°, 99.7901°. This earthquake was detected by 52 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.
