2021-05-26 22:36:21 UTC (2021-05-26) · approx. 12:36 PM UTC-10 local
On May 26, 2021 at 22:36 UTC, a magnitude 2.9 shallow crustal earthquake struck 19 km E of Kalaoa, Hawaii, at a depth of 21.7 km and coordinates 19.7582°, -155.8000°.
Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 374 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 63 m — a useful intuition for the size of the slip patch on the fault.
