M3.4 Earthquake 78 km SSW of Mākena, Hawaii — December 7, 2023
2023-12-07 18:54:15 UTC (2023-12-07) · approx. 8:54 AM UTC-10 local
On December 7, 2023 at 18:54 UTC, a magnitude 3.4 shallow crustal earthquake struck 78 km SSW of Mākena, Hawaii, at a depth of 38.1 km and coordinates 20.0155°, -156.7603°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 2.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 140 m — a useful intuition for the size of the slip patch on the fault.
