M4.3 Earthquake in the Fiji region — June 14, 2023
2023-06-14 19:36:28 UTC (2023-06-14) · approx. 7:36 AM UTC-12 local
On June 14, 2023 at 19:36 UTC, a magnitude 4.3 deep-focus earthquake struck in the Fiji region, at a depth of 561.5 km and coordinates -20.4174°, -178.1588°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
