At the PoRO Lab we study how the physical properties of rocks are reflected in geophysical signatures by combining elastic laboratory experiments, geophysical well logs and field data. We are passionate to explore any cool topic that relates rocks, gadgets, high pressures and fluids! We are close collaborators of the Physical Acoustics Lab.

Together with Kasper van Wijk, Dan Hikuroa and collaborators we love to ImagePOROLABenlighten kids about the geophysics and geoscience through the Seismometers in New Zealand Schools project: Ru. Finally, communicating (geo)science to people anywhere between 5 and 90 years old makes my day! (including our two little kids!)



  • Shreya's GRL paper on volcanic conduit alteration is out!
      Congratulations to Shreya Kanakiya for publishing her first paper of her PhD thesis! This is one of many to come ... Her Geophysical Research Letters publication entitled The Role of Tuffs in Sealing Volcanic Conduits describes how acid-sulphate alteration aids the sealing of a volcanic conduit. She presents evidence of how this type of…
  • Congratulations to James Clarke
      Three out of three! Congratulations to James Clarke for publishing his third manuscript entitled LP or VT signals? How intrinsic attenuation influences volcano seismic signatures constrained by Whakaari volcano parameters in JVGR. In this study we show how seismic wave attenuation and reverberations due to a shallow low-velocity layer can transform volcano-tectonic signals into…
  • Congratulations to Jirapat Charoensawan
    Congratulations to Jirapat (Patt) for the publication of his Msc thesis as a journal article in Frontiers of  Earth Sciences. The numerical simulations and experiments show how the the contribution of mineral anisotropy vs that of oriented fractures influence elastic wave anisotropy for Alpine Fault mylonite rocks. The paper is entitled Fracture Shape and Orientation…
  • Seismic wave attenuation in volcanic rocks
    Congratulations to James Clarke for the publication of his second paper in JVGR from his doctoral thesis entitled The influence of fluid type on elastic wave velocity and attenuation in volcanic rocks
  • Seismic signatures of protomylonite rocks in the Alpine Fault accepted in JGR
    A team effort across several universities (Otago, EHT, Durham and Johannes Gutenberg Universitat-Mainz) has resulted in a publication accepted in the Journal of Geophysical Research entitled Seismic anisotropy and its impact on imaging the shallow Alpine Fault: an experimental and modeling perspective. We show that microfractures in Alpine Fault protomylonite rocks can remain open at…
