On February 19, 2021 at 18:28 UTC, a magnitude 4.1 shallow crustal earthquake struck 70 km SSE of Lethem, Guyana, at a depth of 15.5 km and coordinates 2.7687°, -59.6306°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
