Resistivity and magnetic profiles of TEO-1. Resistivity was measured using a Wenner array. Dashed line: total electric anomaly, square plus line: residual electrical anomaly, continuous line: magnetic profile. The large box marks the zone of interest. The smaller box shows the tunnel's position where it crosses the profile. The magnetic low of the total anomaly reduced-to-the-pole is correlated with the tunnel, whereas the residual electrical anomaly shows it as a slight resistivity high.
