2D P-wave velocity model of the northern Hikurangi margin.

You should find three files attached that include (1) a table that maps x-coordinates to longitude/latitude, (2) the Vp model with columns for x, depth, and Vp, and (3) a table of interfaces that include the topography (value 1) and the Moho (value 2). The zero x coordinate is arbitrarily the location of the westernmost shot in the Bay of Plenty from the SHIRE seismic survey of 2017, so x values range from ~190 to 400 km.

This P-wave velocity model is presented in: Gase, Andrew C., et al. "Crustal structure of the northern Hikurangi margin, New Zealand: Variable accretion and overthrusting plate strength influenced by rough subduction." Journal of Geophysical Research: Solid Earth 126.5 (2021): e2020JB021176.
