Country:New Zealand
Geodetic measurements?Yes

Inferred cause(s) of deformation:Hydrothermal
Characteristics of deformation:

Hole et al. (2007) present InSAR data spanning 1996 to 2005 and detect deformation within five of the heavily utilised geothermal fields of the Taupo Volcanic Zone. “Subsidence signals were identified at the Ohaaki geothermal field from 1999–2004, and at Wairakei–Tauhara from 1996–2005, where our measurements compare well with coeval levelling data across the wider deformation field. Subsidence was also measured at Rotorua from 1996–2000”.
GNS conducts permanent volcanic monitoring and surveillance at all active and potentially active volcanoes in New Zealand.
