2023-05-05 19:35:45 UTC (2023-05-05) · approx. 9:35 AM UTC-10 local
On May 5, 2023 at 19:35 UTC, a magnitude 2.3 shallow crustal earthquake struck 4 km WSW of Kealakekua, Hawaii, at a depth of 8.2 km and coordinates 19.5090°, -155.9630°.
Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 45.5 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.
