M3.6 Earthquake 25 km WNW of Kalaoa, Hawaii — June 10, 2025
2025-06-10 23:01:09 UTC (2025-06-10) · approx. 1:01 PM UTC-10 local
On June 10, 2025 at 23:01 UTC, a magnitude 3.6 shallow crustal earthquake struck 25 km WNW of Kalaoa, Hawaii, at a depth of 41.6 km and coordinates 19.7775°, -156.2217°. The earthquake was reported felt by 5 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 2.9 (weak).
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 181 m — a useful intuition for the size of the slip patch on the fault.
