2020-11-27 18:18:02 UTC (2020-11-27) · approx. 7:18 AM UTC-11 local
On November 27, 2020 at 18:18 UTC, a magnitude 3.2 intermediate depth earthquake struck 64 km SSW of False Pass, Alaska, at a depth of 72.8 km and coordinates 54.3146°, -163.7543°.
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.
