On September 16, 2026 at 21:50 UTC, a magnitude 2.9 shallow crustal earthquake struck 5 km SSW of Assaria, Kansas, at a depth of 9.7 km and coordinates 38.6386°, -97.6344°. This earthquake was detected by 29 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 135, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 338 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 60 m — a useful intuition for the size of the slip patch on the fault.
