Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.2 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 212 m — a useful intuition for the size of the slip patch on the fault.
