2021-10-24 18:17:19 UTC (2021-10-24) · approx. 2:17 AM UTC+8 local
On October 24, 2021 at 18:17 UTC, a magnitude 4.1 shallow crustal earthquake struck 5 km NNE of Kaohsiung, Taiwan, at a depth of 10.0 km and coordinates 22.6628°, 120.3248°.
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.
