On January 26, 2021 at 21:54 UTC, a magnitude 4.3 shallow crustal earthquake struck 2 km WNW of Atarfe, Spain, at a depth of 10.0 km and coordinates 37.2371°, -3.7155°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
