Description

21-May-2022  There are updated Vp and Vp/Vs models 2.3, which incorporate the results from the Southern South Island region, at zenodo.org/record/6568301

13-July-2021  There are updated Qp and Qs models 2.3, which incorporate the results from the Kaikoura region, at zenodo.org/record/5098356

May 2020.  This model has now been updated. Please see NZwide2.2 model which contains 3D seismic velocity and Qs and Qp models, incorporating recent regional 3D studies, at zenodo.org/record/3779523

----------------------------------------

New Zealand Wide model 2.1 has a seismic velocity model for New Zealand, developed from local-earthquake tomography studies.  It is updated to include the Otago model (Reyners et al., 2017).
