M3.3 Earthquake 124 km E of McCarthy, Alaska — March 14, 2025
2025-03-14 19:15:19 UTC (2025-03-14) · approx. 10:15 AM UTC-9 local
On March 14, 2025 at 19:15 UTC, a magnitude 3.3 shallow crustal earthquake struck 124 km E of McCarthy, Alaska, at a depth of 5.2 km and coordinates 61.3130°, -140.6155°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
