On March 29, 2023 at 22:55 UTC, a magnitude 4.5 shallow crustal earthquake struck 108 km SSW of Al Wajh, Saudi Arabia, at a depth of 9.1 km and coordinates 25.3304°, 36.0793°. This earthquake was detected by 45 seismic stations with good 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.
