2022-05-04 21:32:38 UTC (2022-05-04) · approx. 9:32 AM UTC-12 local
On May 4, 2022 at 21:32 UTC, a magnitude 4.4 shallow crustal earthquake struck east of the North Island of New Zealand, at a depth of 38.2 km and coordinates -35.1266°, -179.8994°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
