Plan view of CRT input and output models using checkerboxes about 3 km to a side. The checkerboxes in the input model are embedded in the depth range from 6 to 9 km bsl, and those in the output models are shown at the depth of 7.5 km bsl. Input checkerbox resistivity (red) is 1 Ωm and other blocks are 1000 Ωm except ocean (0.3333 Ωm) and air blocks (1012 Ωm). The output models are shown at the same number of iterations of the final model at each prior model update. The solid lines show the calculation mesh. The white contour represents surface topography. The NS, EW coordinates are set using Oana Crater’s location as the origin
