On May 11, 2021 at 16:52 UTC, a magnitude 4.6 shallow crustal earthquake struck 39 km NE of Al Hoceïma, Morocco, at a depth of 5.3 km and coordinates 35.4606°, -3.5802°.
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.
