We are very interested in extracting information from scattered waves in heterogeneous media. Indoors, these waves have ultrasonic frequencies, excited and detected with lasers. Outside, our waves are in the seismic frequency band.

Seismic Station AUCK is part of our Ru Network of school seismometers

As our wavelengths span orders of magnitudes, so do our applications. Outside, we target the Auckland Volcanic Field, as well as geothermal exploration, and micro-seismicity for fluid reservoir characterization. In the laboratory, we do rock physics in collaboration with the PORO lab, ice physics, and medical imaging.


  • Picking arrivals from 1D-Earth model
    We attempt to present the first arrival times predicted from the ak135 model of several sample earthquakes. We use obspy to aid us with the process. Local and teleseismic events alike are computed in two separate run of the code, with corresponding lines altered accordingly. Due to the nature of the arrivals which are mostly…
  • AVF real data tomography - early test
    We have successfully performed a trial run of tomography in the AVF using real data information. We combined pick time information of 2 local events (one shallow and one deep) and 1 teleseismic earthquake. Residual travel-times were obtained in relative to ak135 1D Earth model predicted times. The following are the…
  • Joint Inversion - finer resolution checker-board
    Our previous joint inversion of assessing the resolution of tomography in the Auckland Volcanic Field gives us promising results for subsurface features at the scale of ~60 km (see this post). The latest checker-board test to improve from this finding involve using smaller sized checker-board, around half of the previous test. The same receivers configuration…
