| Abstract | Beneath the Taupo Volcanic Zone (TVZ), rocks above the brittle-ductile transition (~7 km depth) have potential to provide a long-term geothermal energy resource for New Zealand. To investigate structures at depths down to ~7 km, detailed passive-seismic and magnetotelluric (MT) data have been collected in the southeastern TVZ. This paper describes the MT data analysis and shows detailed 2-D and initial 3-D inverse resistivity models of profiles that transect the Rotokawa and Ohaaki geothermal systems. |
