ERT

The Electrical Resistivity Tomography ERT is based on a multielectrode device allowing the acquisition of apparent electrical resistivities at depth. Many configurations are available (Schlumberger, Wenner, etc.), characterized especially by different investigation depth, resolution and area prospected. Previous works based on ERT (V. Lapenna et al, 2003 ; T. Lebourg et al, 2005 ; H. Jomard, 2006) underline the possibility of acquiring datasets concerning fault geometry, sliding surfaces and water flow circulations down to 300 m below the surface.
