M3.0 Earthquake 3 km SSW of Pāhala, Hawaii — February 21, 2024
2024-02-21 17:36:51 UTC (2024-02-21) · approx. 7:36 AM UTC-10 local
On February 21, 2024 at 17:36 UTC, a magnitude 3.0 shallow crustal earthquake struck 3 km SSW of Pāhala, Hawaii, at a depth of 30.3 km and coordinates 19.1743°, -155.4857°.
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.
