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

  • 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 ...
  • Our computing environment As 21st century researchers, we have access to a tremendous amount of software to practice our trade. In fact, it seems every day new software appears (and some old favourites go out of style, or cease to be supported). ¬†Below is a list of my personal favourites. The common thread here is that these are ...
  • Our “seismometers in schools” project received SEG support and is in the news One of our favourite projects in the Physical Acoustics Lab involves outreach and education in seismology with the TC1 seismometer. This week has been a good week, as we were informed that the Foundation of the Society of Exploration Geophysicists (SEG) will support the instrumentation of a number of NZ schools with seismometers. In addition, ...
