2024-05-27 18:02:15 UTC (2024-05-27) · approx. 8:02 AM UTC-10 local
On May 27, 2024 at 18:02 UTC, a magnitude 3.1 shallow crustal earthquake struck 202 km SE of Perryville, Alaska, at a depth of 7.1 km and coordinates 54.7094°, -156.7597°.
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.
