On October 9, 2022 at 22:53 UTC, a magnitude 3.1 shallow crustal earthquake struck 3 km WSW of Volcano, Hawaii, at a depth of 2.7 km and coordinates 19.4277°, -155.2633°.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 629 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 80 m — a useful intuition for the size of the slip patch on the fault.
