2021-12-25 23:43:35 UTC (2021-12-25) · approx. 5:43 PM UTC-6 local
On December 25, 2021 at 23:43 UTC, a magnitude 2.0 shallow crustal earthquake struck 2 km SSW of Marion, Kansas, at a depth of 5.0 km and coordinates 38.3290°, -97.0294°.
Physical scale: An earthquake of magnitude 2.0 releases seismic energy equivalent to roughly 15.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 14 m — a useful intuition for the size of the slip patch on the fault.
