PAL Home

In the Physical Acoustics Laboratory (PAL), we are interested in extracting information from scattered waves in heterogeneous media. Indoors, these waves are of ultrasonic frequencies, excited and detected with lasers. Outside, our waves are in the seismic frequency band.

Seismic Station AUCK is our home-built TC1 seismometer on campus

As our wavelengths span orders of magnitudes, so do our applications. Outside, we study CO2 sequestration and geothermal exploration, as well as micro-seismicity for fluid reservoir characterization. In the laboratory, we do rock physics, ice core tomography, and medical imaging.

News & Announcements

  • Leighton is famous (on the North Shore, at least) One of our PALs — Leighton Watson — is featured in the North Shore Times, showing this is not just some door-to-door rag, but a bastion of high-quality journalism, tailoring to the well-educated. When he wraps up his Honours project, he’ll be famous among rock physicists as well….. In any case, congrats to Leighton and ...
  • Seismic Monitoring the Auckland Volcanic Field Auckland may be the only metropolis built on top of an active — in geologic terms — volcanic field: The Auckland Volcanic FieldĀ (AVF). This was recognized a long time ago, and GeoNet has instrumented the area with a regional network of seismometers, regional network name AK. GeoNet’s seismologists carefully monitor the AVF with this network, while ...
  • A deep earthquake on the eastern margin of the Australian plate Yesterday, we recorded seismic waves on our station AUCK from an Earthquake roughly 11 degrees to our North. This event is characterized by a strong P- and S-wave arrival as you can see in this figure: Given the usual limitations of our (vertical) sensor when it comes to S-wave recordings, this is indicative of a very ...
