“…It calculates the correlation between the observed surface potentials and the potential from a scanning test charge. This technique has successfully been used to map the subsurface charge distributions of the Vesuvius volcano (Patella, 1997b) and the Varco d'Izzo landslide (Perrone et al, 2004).…”

We present a comparison of the abilities of Electrical Resistivity Tomography (ERT) and Self-Potential Tomography (SPT) to detect and characterize buried mineshafts at the site of a former colliery. Surface electrical resistivity and self-potential (SP) surveys were carried out at two test sites, each containing a hidden shaft. The ERT survey results indicate that both sites had a highly heterogeneous subsurface resistivity distribution, which we attribute to colliery spoil and former infrastructure. ERT managed to distinguish an air-filled, highly resistive mineshaft from this background, but failed to detect the second shaft, which was backfilled and therefore had a much lower resistivity contrast with the surrounding formation. However, SPT located both shafts, gave an indication of their size, shape and depth of burial, and was able to distinguish the openfrom the backfilled mineshaft due to the strength of the associated SP anomalies. We argue that these SP anomalies are likely to be due to changes in the streaming potential caused by preferential drainage into the shafts.

“…Recently there has been renewed interest in the use of SP data for geohazard monitoring (Patella, 1997b;Perrone et al, 2004). But, despite the fact that SP surveying is quick and inexpensive, its use in environmental and engineering site investigation has not been widely appreciated (Nyquist and Corry, 2002).…”

“…Friedel et al, 2006); SP surveys were undertaken to identify groundwater seepage pathways associated with the slide (e.g. Perrone et al, 2004). In terms of coverage, the purpose of the resistivity mapping survey, the 2D ERT lines and SP profiles was to provide geophysical data across the whole of the Hollin Hill research site.…”

“…In the last few years, the ERT has been increasingly applied to study active faults (Galli et al, 2006(Galli et al, , 2014Improta et al, 2010;Giocoli et al, 2011), volcanic areas (Finizzola et al, 2010Siniscalchi et al, 2010), landslides (Perrone et al, 2004), geological and structural setting of sedimentary basins (Giocoli et al, 2008), local seismic response (Boncio et al, 2011;Mucciarelli et al, 2011;Moscatelli et al, 2012), etc. Only in very few cases was the ERT method applied in laboratory experiments in order to study liquefaction phenomenon during and after the shaking (Jinguuji et al, 2007).…”

Abstract. This work shows the result of an electrical resistivity tomography (ERT) survey carried out for imaging and characterizing the shallow subsurface affected by the coseismic effects of the Mw = 6.1 Emilia-Romagna (northern Italy) earthquake that occurred on 20 May 2012. The most characteristic coseismic effects were ground failure, lateral spreading and liquefaction that occurred extensively along the paleo-Reno River in the urban areas of San Carlo and Mirabello (southwestern portion of Ferrara Province). In total, six electrical resistivity tomographies were performed and calibrated with surface geological surveys, exploratory boreholes and aerial photo interpretations. This was one of first applications of the electrical resistivity tomography method in investigating coseismic liquefaction.
