2020-07-26 23:48:19 UTC (2020-07-26) · approx. 1:48 PM UTC-10 local
On July 26, 2020 at 23:48 UTC, a magnitude 3.6 intermediate depth earthquake struck 58 km ESE of Pedro Bay, Alaska, at a depth of 109.9 km and coordinates 59.6425°, -153.1151°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 184 m — a useful intuition for the size of the slip patch on the fault.
