On July 5, 2026 at 15:03 UTC, a magnitude 4.9 shallow crustal earthquake struck 27 km NW of Mianzhu, Deyang, Sichuan, China, at a depth of 10.0 km and coordinates 31.5295°, 104.0430°. This earthquake was detected by 75 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 370, 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.
