On April 22, 2026 at 07:15 UTC, a magnitude 4.5 shallow crustal earthquake struck 48 km NE of Luocheng, China, at a depth of 10.0 km and coordinates 29.7470°, 104.3123°. This earthquake was detected by 43 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
