M2.5 Earthquake in the Maui region, Hawaii — January 23, 2023
2023-01-23 20:12:38 UTC (2023-01-23) · approx. 10:12 AM UTC-10 local
On January 23, 2023 at 20:12 UTC, a magnitude 2.5 shallow crustal earthquake struck in the Maui region, Hawaii, at a depth of 4.5 km and coordinates 20.2938°, -156.6108°.
Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 87.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 33 m — a useful intuition for the size of the slip patch on the fault.
