M4.0 Earthquake south of the Fiji Islands — July 15, 2024
2024-07-15 21:41:59 UTC (2024-07-15) · approx. 9:41 AM UTC-12 local
On July 15, 2024 at 21:41 UTC, a magnitude 4.0 deep-focus earthquake struck south of the Fiji Islands, at a depth of 565.6 km and coordinates -23.1832°, -179.6937°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
