On October 22, 2023 at 15:14 UTC, a magnitude 5.0 shallow crustal earthquake struck 70 km SW of Laojunmiao, China, at a depth of 10.0 km and coordinates 39.3155°, 97.2486°. This earthquake was detected by 70 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.
