Felt by 11 people across nearby locations.
On October 22, 2023 at 19:20 UTC, a magnitude 4.8 shallow crustal earthquake struck 53 km SE of Huanggang, China, at a depth of 10.0 km and coordinates 23.3544°, 117.3907°. This earthquake was detected by 93 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 361, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
