2024-07-25 21:46:31 UTC (2024-07-25) · approx. 11:46 AM UTC-10 local
On July 25, 2024 at 21:46 UTC, a magnitude 3.1 shallow crustal earthquake struck 6 km SSW of Volcano, Hawaii, at a depth of 1.4 km and coordinates 19.3897°, -155.2477°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 722 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 86 m — a useful intuition for the size of the slip patch on the fault.
