2020-11-05 18:26:17 UTC (2020-11-05) · approx. 5:26 AM UTC+11 local
On November 5, 2020 at 18:26 UTC, a magnitude 4.0 shallow crustal earthquake struck 3 km E of Burnham, New Zealand, at a depth of 10.0 km and coordinates -43.6132°, 172.3557°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
