On May 2, 2023 at 20:15 UTC, a magnitude 3.3 shallow crustal earthquake struck 39 km SSW of Eureka, Nevada, at a depth of 0.0 km and coordinates 39.1914°, -116.1556°.

Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
