2020-08-03 22:50:33 UTC (2020-08-03) · approx. 12:50 PM UTC-10 local
On August 3, 2020 at 22:50 UTC, a magnitude 3.1 shallow crustal earthquake struck 52 km NNW of Venetie, Alaska, at a depth of 19.4 km and coordinates 67.4487°, -146.8604°.
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.
