On July 13, 2024 at 22:49 UTC, a magnitude 4.5 shallow crustal earthquake struck 189 km ENE of Saga, China, at a depth of 10.0 km and coordinates 30.0913°, 86.9812°. This earthquake was detected by 60 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.
