Probing the subsurface of the Auckland Volcanic Field with ambient seismic noise
New Zealand Journal of Geology, and Geophysics, 2017ABSTRACT Current understanding of the Auckland Volcanic Field is predominantly based on geological and geochemical observations from the surface. Low local seismicity hinders passive seismic imaging efforts, whereas strong shallow heterogeneity reduces the resolution and penetration of active seismic models.

Elliptical boundary of an intraplate volcanic field, Auckland, New Zealand
Journal of Volcanology and Geothermal Research, 1997Abstract The outer vents in the Auckland Volcanic Field lie within 19 to 559 m (mean 224.75 m) of a `best-fit' ellipse with a 28.9-km-long major axis trending almost north–south, and a minor axis 16.5 km long. The ellipse has formed the outer boundary of the field since the inception of volcanism 140,000 years ago.

Monitoring seismic precursors to an eruption from the Auckland Volcanic Field, New Zealand
New Zealand Journal of Geology, and Geophysics, 2007Abstract The Auckland Volcanic Field (AVF) in New Zealand is monitored by a network of five telemetered, vertical‐component, short‐period seismographs. Between 1995 and 2005, 24 earthquakes were located in the Auckland region.

The city of Auckland (population 1.3 million) is built on and around a potentially active basaltic intraplate volcanic system, the Auckland volcanic field. This monogenetic field of around 50 small volcanoes covers an area of 360 km2 and may have been active for ca. 250 ka.

Gravity and magnetic investigation of maar volcanoes, Auckland volcanic field, New Zealand
Journal of Volcanology and Geothermal Research, 2007Abstract Detailed gravity and aeromagnetic data over maars in the Auckland volcanic field reveal contrasting anomalies, even where surface geology is similar. Pukaki and Pukekiwiriki, almost identical maars marked by sediment-filled craters and tuff rings, have gravity and magnetic anomalies of − 6 g.u. and 20 nT, and 8 g.u. and 160 nT, respectively.

Auckland Volcanic Field magmatism, volcanism, and hazard: a review
New Zealand Journal of Geology and Geophysics, 2020ABSTRACT Auckland Volcanic Field (AVF) is a basaltic intraplate volcanic field in North Island, New Zealand, upon which >1.6 million people live. Seismic velocity tomography and geochemistry suggest a primary mantle source region at a depth of 70–90 km.
