Statement

Time-series records of the magnetic and electric fields measured at the AusLAMP MT sites were QA\QCed, pre-processed and transformed into the frequency domain (Kyi et al, 2020). Data were then inverted to a 3D resistivity voxet model of the crust using the ModEM 3D code on the National Computing Infrastructure supercomputer (Kirkby et al, submitted). The 3D resistivity model was sliced to display the voxet cells at 10 km depth in plan-view. The cells were coloured according to their resistivity value to create the image.
