On February 16, 2022 at 04:32 UTC, a magnitude 4.9 shallow crustal earthquake struck in the Madeira Islands, Portugal region, at a depth of 11.7 km and coordinates 32.3503°, -16.9067°.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
