On January 10, 2023 at 20:25 UTC, a magnitude 4.6 shallow crustal earthquake struck 48 km NE of Jiangyou, China, at a depth of 13.3 km and coordinates 32.0539°, 105.0998°. This earthquake was detected by 96 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
