M3.7 Earthquake 44 km ENE of Adak, Alaska — March 6, 2025
2025-03-06 17:33:20 UTC (2025-03-06) · approx. 5:33 AM UTC-12 local
On March 6, 2025 at 17:33 UTC, a magnitude 3.7 shallow crustal earthquake struck 44 km ENE of Adak, Alaska, at a depth of 43.3 km and coordinates 52.0211°, -176.0334°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — a useful intuition for the size of the slip patch on the fault.
