Resistivity and magnetic profiles of TEO-5. Resistivity was measured using a Wenner array. Dashed line: total electric anomaly, square plus line: residual electrical anomaly, continuous line: magnetic profile. The zone marked with a letter "A" shows a magnetic minimum that is not correlated with the electrical anomaly. It may represent a filled depression. The area marked with a box, where the magnetic minimum is correlated with the electrical anomaly, reveals the possible presence of a tunnel.
