2020-06-23 21:49:40 UTC (2020-06-23) · approx. 1:49 PM UTC-8 local
On June 23, 2020 at 21:49 UTC, a magnitude 2.5 shallow crustal earthquake struck 20 km NW of Stanley, Idaho, at a depth of 10.0 km and coordinates 44.3268°, -115.1487°.
Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 84.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 32 m — a useful intuition for the size of the slip patch on the fault.
