On October 12, 2022 at 10:02 UTC, a magnitude 4.7 shallow crustal earthquake struck near northern Qinghai, China, at a depth of 10.0 km and coordinates 36.9227°, 95.7811°. This earthquake was detected by 32 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
