M3.0 Earthquake 48 km ESE of Naalehu, Hawaii — April 26, 2025
2025-04-26 17:45:07 UTC (2025-04-26) · approx. 7:45 AM UTC-10 local
On April 26, 2025 at 17:45 UTC, a magnitude 3.0 shallow crustal earthquake struck 48 km ESE of Naalehu, Hawaii, at a depth of 9.6 km and coordinates 18.8285°, -155.1940°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 511 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 73 m — a useful intuition for the size of the slip patch on the fault.
