M4.9 Earthquake in the Kermadec Islands region — April 24, 2026
2026-04-24 18:22:32 UTC (2026-04-24) · approx. 6:22 AM UTC-12 local
On April 24, 2026 at 18:22 UTC, a magnitude 4.9 intermediate depth earthquake struck in the Kermadec Islands region, at a depth of 89.9 km and coordinates -31.0303°, -178.3316°. This earthquake was detected by 109 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
