2020-11-11 19:50:24 UTC (2020-11-11) · approx. 9:50 AM UTC-10 local
On November 11, 2020 at 19:50 UTC, a magnitude 3.1 shallow crustal earthquake struck near Island of Hawaii, Hawaii, at a depth of 1.8 km and coordinates 19.3915°, -155.2473°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 722 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 86 m — a useful intuition for the size of the slip patch on the fault.
