Abstract:

The data files are results of seismic inversions carried out with seismic reflection data from the Tuaheni Landslide Complex, east of New Zealand's North Island on the Hikurangi Margin. The starting models and inversion results were created using an academic license to the HampsonRussell software, provided to GEOMAR Helmholtz Centre for Ocean Research Kiel. The results are presented in Crutchley et al. 2021 (doi:10.1029/2021JB021997).
