2021-03-10 22:47:38 UTC (2021-03-10) · approx. 2:47 PM UTC-8 local
On March 10, 2021 at 22:47 UTC, a magnitude 3.0 shallow crustal earthquake struck 32 km NW of Stanley, Idaho, at a depth of 13.7 km and coordinates 44.4479°, -115.1891°.
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.
