On April 29, 2026 at 19:11 UTC, a magnitude 4.7 shallow crustal earthquake struck 74 km N of Yongning, China, at a depth of 10.0 km and coordinates 28.4911°, 100.8041°. This earthquake was detected by 118 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
