M6.5 Earthquake in the Kermadec Islands region — January 29, 2022
2022-01-29 02:46:39 UTC (2022-01-29) · approx. 2:46 PM UTC-12 local
Felt by 2 people across nearby locations.
On January 29, 2022 at 02:46 UTC, a magnitude 6.5 shallow crustal earthquake struck in the Kermadec Islands region, at a depth of 8.0 km and coordinates -29.5642°, -176.7217°. The earthquake was reported felt by 2 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.7 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected.
Physical scale: An earthquake of magnitude 6.5 releases seismic energy equivalent to roughly 85 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 18 km — a useful intuition for the size of the slip patch on the fault.
