M4.7 Earthquake in the Kermadec Islands region — June 6, 2020
2020-06-06 09:40:05 UTC (2020-06-06) · approx. 9:40 PM UTC-12 local
On June 6, 2020 at 09:40 UTC, a magnitude 4.7 shallow crustal earthquake struck in the Kermadec Islands region, at a depth of 10.0 km and coordinates -31.3573°, -177.9204°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
