M5.0 Earthquake in the Kermadec Islands region — May 19, 2025
2025-05-19 23:31:30 UTC (2025-05-19) · approx. 11:31 AM UTC-12 local
On May 19, 2025 at 23:31 UTC, a magnitude 5.0 intermediate depth earthquake struck in the Kermadec Islands region, at a depth of 95.5 km and coordinates -31.0643°, -178.4757°. This earthquake was detected by 51 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
