On October 29, 2021 at 06:10 UTC, a magnitude 4.7 shallow crustal earthquake struck 9 km ENE of Bulqizë, Albania, at a depth of 10.0 km and coordinates 41.5207°, 20.3353°.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
