2024-07-31 20:13:45 UTC (2024-07-31) · approx. 10:13 AM UTC-10 local
On July 31, 2024 at 20:13 UTC, a magnitude 3.1 shallow crustal earthquake struck 6 km S of Volcano, Hawaii, at a depth of 1.6 km and coordinates 19.3840°, -155.2410°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 651 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 82 m — a useful intuition for the size of the slip patch on the fault.
