2022-12-05 18:42:40 UTC (2022-12-05) · approx. 8:42 AM UTC-10 local
On December 5, 2022 at 18:42 UTC, a magnitude 2.2 shallow crustal earthquake struck 28 km E of Honaunau-Napoopoo, Hawaii, at a depth of -0.8 km and coordinates 19.4732°, -155.5927°.
Physical scale: An earthquake of magnitude 2.2 releases seismic energy equivalent to roughly 25.3 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 18 m — a useful intuition for the size of the slip patch on the fault.
