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 in collaboration with the PORO lab, ice core tomography, and medical imaging.

News & Announcements

  • Medical imaging in the Physical Acoustics Lab The latest issue of the Journal of Biomedical Optics features an article led by Jami Johnson, in collaboration with our good friend Jeffrey Shragge (from the University of Western Australia). In it, we apply some the latest tricks stemming from seismology to medical imaging of arteries. This particular publication focuses on theory and numerical simulations, ...
  • Ru in the European Journal of Physics The March issue of The European Journal of Physics features a review article on Ru: the seismic network of school seismometers in New Zealand. The journal (and hence our paper) targets Physics students in their final year(s) in secondary education, or early tertiary education, but we hope it appeals to a broad range of readers! ...
  • Seismology in Python: obspy for (and by) beginners This is an intro to ┬ásome basic tasks in seismology, performed in the python package obspy. Obspy has extensive documentation, tutorials and even a sandbox to play in, but if you are completely new to obspy, you may find the following useful. Installations I am going to assume you only have python on your computer, but if ...
