2023-07-06 18:03:55 UTC (2023-07-06) · approx. 2:03 AM UTC+8 local
On July 6, 2023 at 18:03 UTC, a magnitude 4.3 shallow crustal earthquake struck 78 km E of Yujing, Taiwan, at a depth of 15.1 km and coordinates 23.1066°, 121.2292°.
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.
