M3.1 Earthquake 98 km E of Red Dog Mine, Alaska — June 24, 2022
2022-06-24 19:14:11 UTC (2022-06-24) · approx. 8:14 AM UTC-11 local
On June 24, 2022 at 19:14 UTC, a magnitude 3.1 shallow crustal earthquake struck 98 km E of Red Dog Mine, Alaska, at a depth of 13.2 km and coordinates 68.0777°, -160.5193°.
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.
