M4.0 Earthquake south of the Fiji Islands — August 24, 2020
2020-08-24 21:43:07 UTC (2020-08-24) · approx. 9:43 AM UTC-12 local
On August 24, 2020 at 21:43 UTC, a magnitude 4.0 deep-focus earthquake struck south of the Fiji Islands, at a depth of 465.1 km and coordinates -25.5591°, -179.8768°.
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.
