2020-08-29 17:14:03 UTC (2020-08-29) · approx. 5:14 AM UTC+12 local
On August 29, 2020 at 17:14 UTC, a magnitude 4.4 deep-focus earthquake struck south of the Fiji Islands, at a depth of 564.1 km and coordinates -23.3051°, 179.4961°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
