2022-05-23 19:45:23 UTC (2022-05-23) · approx. 9:45 AM UTC-10 local
On May 23, 2022 at 19:45 UTC, a magnitude 3.8 intermediate depth earthquake struck 59 km SE of Denali National Park, Alaska, at a depth of 127.0 km and coordinates 63.2190°, -150.7688°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
