2024-04-27 19:50:24 UTC (2024-04-27) · approx. 9:50 AM UTC-10 local
On April 27, 2024 at 19:50 UTC, a magnitude 3.0 intermediate depth earthquake struck 61 km NNE of Petersville, Alaska, at a depth of 106.0 km and coordinates 63.0159°, -150.3532°.
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.
