On December 16, 2024 at 00:09 UTC, a magnitude 5.0 shallow crustal earthquake struck 17 km ENE of Sidi Akkacha, Algeria, at a depth of 9.3 km and coordinates 36.5002°, 1.4923°. This earthquake was detected by 54 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 394, placing it among routine seismic activity.
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.
