A detailed study of the ancient and modern topography of New Zealand’s most populous city, Auckland, has revealed significant concealed fault offsets beneath the region’s volcanic field deposits.

Research on all aspects of monogenetic (small-volume) volcanism has been presented at the Fourth International Maar Conference (4IMC) in Auckland.
The scale of eruption in the Auckland Volcanic Field (AVF) appears to be controlled by the dynamics of the soft area (asthenosphere) of the upper mantle.
The orientation of horizontal components of borehole seismometers is unknown on installation.
However, it is crucial to any multicomponent seismic analysis.
