Electrical resistivity tomography for studying liquefaction induced by the May 2012 Emilia-Romagna earthquake (Mw = 6.1, northern Italy) [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2014
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 ...

Evaluation of Artifacts and Misinterpretation in 2D Electrical Resistivity Tomography Caused by Three-Dimensional Resistive Structures of Regular or Irregular Shapes

open access: yesApplied Sciences, 2023
Electrical resistivity tomography (ERT) is a well-known geophysical method applied to geological, hydrogeological and geoenvironmental research. To date, 2D ERT is still used much more than 3D ERT, thanks to its greater immediacy, survey speed and lower ...

Heat as a proxy to image dynamic processes with 4D electrical resistivity tomography [PDF]

open access: yes, 2019
Since salt cannot always be used as a geophysical tracer (because it may pollute the aquifer with the mass that is necessary to induce a geophysical contrast), and since in many contaminated aquifer salts (e.g., chloride) already constitute the main ...

Monitoring hydraulic processes with automated time-lapse electrical resistivity tomography (ALERT) [PDF]

open access: yes, 2009
Hydraulic processes in porous media can be monitored in a minimally invasive fashion by time-lapse electrical resistivity tomography (ERT). The permanent installation of specifically designed ERT instrumentation, telemetry and information technology (IT)

Application of electrical resistivity tomography (ERT) in uranium mining earth dam

open access: yesJournal of Geophysics and Engineering, 2022
Abstract Dams are built to contain water or mining tailings and provide several benefits to society. The safety and stability of these structures are essential since eventual accidents can generate catastrophic damage. The main cause of ruptures is associated with abnormal seepage, which can progress to an internal erosion process.

Multielectrode Geoelectrical Tomography for the Quantification of Plant Roots

open access: yesItalian Journal of Agronomy, 2010
The amount and spatial distribution of plant roots are crucial ecological features, and methods based on soil electrical resistivity (r) tomography (ERT) have been proposed for their non-destructive measurement.

Tomographic inversion of time-domain resistivity and chargeability data for the investigation of landfills using a priori information [PDF]

open access: yes, 2017
In this paper, we present a new code for the modelling and inversion of resistivity and chargeability data using a priori information to improve the accuracy of the reconstructed model for landfill.

Groundwater Pathway Mapping Using Electrical Resistivity Tomography (ERT) Method

open access: yesJournal of Sustainable Underground Exploration, 2021
Geophysical electrical resistivity method has been one of the more popular non-destructive method to explore the subsurface. Geophysical electrical resistivity tomography (ERT) subsurface profiling was conducted to map the groundwater path along the embankment.
