M3.2 Earthquake 69 km ENE of Wrangell, Alaska — July 11, 2022
2022-07-11 19:32:04 UTC (2022-07-11) · approx. 10:32 AM UTC-9 local
On July 11, 2022 at 19:32 UTC, a magnitude 3.2 shallow crustal earthquake struck 69 km ENE of Wrangell, Alaska, at a depth of 1.0 km and coordinates 56.7329°, -131.3574°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
