On July 25, 2020 at 12:13 UTC, a magnitude 4.8 shallow crustal earthquake struck 20 km NNE of Al Hoceïma, Morocco, at a depth of 10.0 km and coordinates 35.4251°, -3.8678°.

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.
