M3.4 Earthquake 47 km NE of Chase, Alaska — January 23, 2025
2025-01-23 15:14:33 UTC (2025-01-23) · approx. 5:14 AM UTC-10 local
On January 23, 2025 at 15:14 UTC, a magnitude 3.4 intermediate depth earthquake struck 47 km NE of Chase, Alaska, at a depth of 75.2 km and coordinates 62.7830°, -149.5169°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
