The Okataina Volcanic Centre (OVC) is one of two large active rhyolite centres located in the Taupo Rift in New Zealand. Limited geodetic studies do not provide a clear understanding of the deformation patterns preceding renewed volcanic activity at the OVC. This knowledge is essential to ensure that geodetic signals from volcanic processes at the OVC are correctly identified and distinguished from non-volcanic signals. This study uses geodetic and geophysical modelling techniques to investigate this problem. The results have important implications for how any future observed ground deformation at the OVC is observed and interpreted.
