On September 27, 2026 at 16:43 UTC, a magnitude 5.0 shallow crustal earthquake struck 191 km NW of Oula Xiuma, China, at a depth of 10.0 km and coordinates 35.3861°, 99.5536°. This earthquake was detected by 55 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
