On January 1, 2025 at 20:57 UTC, a magnitude 3.0 shallow crustal earthquake struck 4 km S of Brownlee, Nebraska, at a depth of 5.0 km and coordinates 42.2506°, -100.6257°. This earthquake was detected by 18 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 142, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
