M3.1 Earthquake 1 km E of P?hala, Hawaii — May 26, 2021
2021-05-26 21:25:47 UTC (2021-05-26) · approx. 11:25 AM UTC-10 local
On May 26, 2021 at 21:25 UTC, a magnitude 3.1 shallow crustal earthquake struck 1 km E of P?hala, Hawaii, at a depth of 36.2 km and coordinates 19.2027°, -155.4653°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 773 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 88 m — a useful intuition for the size of the slip patch on the fault.
