On May 2, 2023 at 15:27 UTC, a magnitude 5.3 shallow crustal earthquake struck 26 km WSW of Bonan, China, at a depth of 10.0 km and coordinates 25.4011°, 99.2692°. This earthquake was detected by 156 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 436, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
