2022-06-21 22:44:16 UTC (2022-06-21) · approx. 12:44 PM UTC-10 local
On June 21, 2022 at 22:44 UTC, a magnitude 2.8 shallow crustal earthquake struck 48 km SSE of Denali National Park, Alaska, at a depth of 10.5 km and coordinates 63.1238°, -151.4771°.
Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 239 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 52 m — a useful intuition for the size of the slip patch on the fault.
