Abstract

•Approach to increase confidence in resistivity structures accuracy and resolution.•These are the first 3D MT inversions of Krafla MT dataset.•Krafla and Hengill resistivity response is similar to other high temperature system.•Low resistivity feature NW of IDDP-1 is interpreted as magma intrusion.•Detailed subsurface resistivity adds to understanding of complex geothermal systems.
