My name is Josiah Ensing and I am a Ph.D. candidate at the University of Auckland. I have a BSc in Earth Sciences from the University of Waikato, and a PGDipSci and MSc in Geophysics from the University of Auckland. My research interests include geohazards and geophysics. My research experience includes imaging the subsurface of the Auckland Volcanic Field using the vertical component cross-correlations of ambient seismic noise, seismometer orientation by p-wave and Rayleigh wave polarisation, and XRD analysis of groundmass crystallinity from basaltic volcanic deposits from the Auckland Volcanic Field.

My PhD research topic is to image the subsurface of the Auckland Volcanic Field using the cross-term cross-correlations of multi-component ambient seismic noise as a source signal. For the first phase of this project I need to estimate the orientations of the borehole seismometers in Auckland.
