2022-01-11 23:02:18 UTC (2022-01-11) · approx. 1:02 PM UTC-10 local
On January 11, 2022 at 23:02 UTC, a magnitude 2.3 shallow crustal earthquake struck 16 km SSE of Fern Forest, Hawaii, at a depth of 1.3 km and coordinates 19.3193°, -155.1020°.
Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 44.0 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 24 m — a useful intuition for the size of the slip patch on the fault.
