On January 14, 2023 at 19:40 UTC, a magnitude 4.3 intermediate depth earthquake struck 75 km E of Jiufen, Taiwan, at a depth of 185.4 km and coordinates 25.1713°, 122.5941°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
