2021-06-22 21:15:09 UTC (2021-06-22) · approx. 1:15 PM UTC-8 local
On June 22, 2021 at 21:15 UTC, a magnitude 2.0 shallow crustal earthquake struck 4 km ESE of Swede Heaven, Washington, at a depth of 14.7 km and coordinates 48.2703°, -121.6675°.
Physical scale: An earthquake of magnitude 2.0 releases seismic energy equivalent to roughly 17.3 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 15 m — a useful intuition for the size of the slip patch on the fault.
