Felt by 13 people across nearby locations.
On March 18, 2021 at 00:17 UTC, a magnitude 5.0 shallow crustal earthquake struck 26 km NE of Bejaïa, Algeria, at a depth of 10.0 km and coordinates 36.9107°, 5.3143°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
