M3.0 Earthquake 17 km N of P?hala, Hawaii — February 16, 2022
2022-02-16 17:28:07 UTC (2022-02-16) · approx. 7:28 AM UTC-10 local
On February 16, 2022 at 17:28 UTC, a magnitude 3.0 shallow crustal earthquake struck 17 km N of P?hala, Hawaii, at a depth of 8.6 km and coordinates 19.3620°, -155.4745°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 494 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 72 m — a useful intuition for the size of the slip patch on the fault.
