2024-04-12 17:55:58 UTC (2024-04-12) · approx. 6:55 AM UTC-11 local
On April 12, 2024 at 17:55 UTC, a magnitude 3.1 intermediate depth earthquake struck 64 km WSW of Dutch Harbor, Alaska, at a depth of 106.1 km and coordinates 53.7281°, -167.4894°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
