On March 18, 2025 at 09:50 UTC, a magnitude 4.8 shallow crustal earthquake struck 19 km SW of Lakhdaria, Algeria, at a depth of 10.0 km and coordinates 36.4349°, 3.4384°. This earthquake was detected by 167 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 372, 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.
