On April 2, 2025 at 18:01 UTC, a magnitude 4.3 shallow crustal earthquake struck 13 km N of Hualien City, Taiwan, at a depth of 36.0 km and coordinates 24.0974°, 121.6118°.0

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.
