2025-03-17 22:45:26 UTC (2025-03-17) · approx. 12:45 PM UTC-10 local
On March 17, 2025 at 22:45 UTC, a magnitude 3.6 shallow crustal earthquake struck 52 km SSE of Denali National Park, Alaska, at a depth of 2.5 km and coordinates 63.0870°, -151.4700°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 184 m — a useful intuition for the size of the slip patch on the fault.
