- •
A new 3D geologically constrained geophysical model of Mount Tongariro is presented.
- •
A better defined basement surface shows volume of volcanics exceeds previous estimates.
- •
Extensive hydrothermal system defines area of landslide and phreatic eruption hazard.
- •
Tectonic faults act as boundaries to hydrothermal system and are unlikely to be magma conduits.
