M5.2 Earthquake in the Kermadec Islands region — July 30, 2026
2026-07-30 17:48:15 UTC (1 hour ago) · approx. 5:48 AM UTC-12 local
On July 30, 2026 at 17:48 UTC, a magnitude 5.2 shallow crustal earthquake struck in the Kermadec Islands region, at a depth of 46.0 km and coordinates -31.3231°, -177.9701°. This earthquake was detected by 23 seismic stations with good 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.
