2023-01-25 21:19:08 UTC (2023-01-25) · approx. 4:19 AM UTC+7 local
On January 25, 2023 at 21:19 UTC, a magnitude 4.4 shallow crustal earthquake struck 26 km SSE of Kangding, China, at a depth of 10.0 km and coordinates 29.7831°, 102.0678°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
