M5.2 Earthquake south of the Kermadec Islands — July 18, 2026
2026-07-18 05:46:47 UTC (2 hours ago) · approx. 5:46 PM UTC-12 local
On July 18, 2026 at 05:46 UTC, a magnitude 5.2 shallow crustal earthquake struck south of the Kermadec Islands, at a depth of 10.0 km and coordinates -32.8189°, -178.1149°. This earthquake was detected by 60 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
