 In the ground beneath Tuzgle, seismic tomography has found a 18-kilometre (11 mi) thick layer of low velocity, probably linked to a lower density of the rock, at a depth of 40 kilometres (25 mi). Magnetotelluric analysis has found several deep (1 – 85 kilometres ( 0.62 – 52.82 mi) ) conductive layers and one shallow one, possibly formed by the aquifers in the area. Another high conductivity body southeast of Tuzgle is associated with the Toro lineament and the Queva volcano and may also be hydrothermal in origin.
