On October 26, 2025 at 15:03 UTC, a magnitude 4.9 shallow crustal earthquake struck 65 km WNW of Daocheng, China, at a depth of 25.1 km and coordinates 29.2614°, 99.6697°. This earthquake was detected by 70 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
