SUMMARY
A magnitude 6.2 earthquake occurred 286 km southwest of Bluff, New Zealand, at a depth of 10.0 km on April 29, 2025, at 13:16:32 UTC. The seismic event produced a significant T-phase detected on geophones in Sydney, indicating its impact on the region. The earthquake's characteristics suggest a strike-slip motion, as confirmed by the Moment Tensor solution. This event is notable for its long-period recording and the propagation directions of initial water movements.
PREREQUISITES
- Understanding of seismic wave types, particularly T-phases.
