On June 26, 2022 at 19:17 UTC, a magnitude 4.6 shallow crustal earthquake struck 14 km NW of Aïn el Bya, Algeria, at a depth of 10.0 km and coordinates 35.9130°, -0.3922°. This earthquake was detected by 39 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 329, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
