2020-06-17 23:03:58 UTC (2020-06-17) · approx. 1:03 PM UTC-10 local
On June 17, 2020 at 23:03 UTC, a magnitude 3.3 intermediate depth earthquake struck 47 km N of Chase, Alaska, at a depth of 80.5 km and coordinates 62.8732°, -149.9733°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
