M3.0 Earthquake south of the Aleutian Islands — March 5, 2025
2025-03-05 15:23:56 UTC (2025-03-05) · approx. 3:23 AM UTC+12 local
On March 5, 2025 at 15:23 UTC, a magnitude 3.0 shallow crustal earthquake struck south of the Aleutian Islands, at a depth of 10.0 km and coordinates 49.9208°, 179.0341°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
