On July 24, 2020 at 19:11 UTC, a magnitude 5.1 shallow crustal earthquake struck 81 km SW of Niquero, Cuba, at a depth of 8.7 km and coordinates 19.4880°, -78.0806°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
